Corrosion had eaten away at the metal, and its once-lustrous finish was now crusty and riddled with ragged holes.\u00a0<\/p>\n<p>I wanted to buy new trim from the factory, but production of the model had long ceased, and no replacement trim was available. Commissioning a custom piece of trim from a fabricator proved a bit too expensive for my budget. \u00a0<\/p>\n<p>Making my own seemed like the way to go. I started with 1-inch aluminum 90-degree angle stock for the straight run across the outboard edge of the transom where the liner meets the hull. On each end of the straight run, however, the transom curves upward to meet the rail cap. Bending the aluminum stock proved too difficult for me, so I turned to another material\u20141-inch PVC 90-degree angle stock\u2014to adjoin and bookend the aluminum trim. The PVC is 3\/16-inch thick, which is drillable and holds fasteners well, and the light-gray color complements my boat and blends well with the aluminum angle stock. It is available in up to 6-foot lengths for $21.08 each from <a href=\"https:\/\/www.grainger.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">grainger.com<\/a>.<\/p>\n<p>PVC angle stock is rigid and chemical-resistant but becomes malleable with the application of mild heat, and so it can conform nicely to inside and outside bends. It returns to a rigid state once it cools. Here are the steps I followed to shape one curving piece of trim, a process that needs to be repeated in a mirror image on the opposite side.<\/p>\n<p><strong>Skill Level:<\/strong> 2.5 of 5<\/p>\n<p><strong>Finish Time:<\/strong> Approx. 3-4 hours per each curved piece of trim<\/p>\n<h2 class=\"wp-block-heading\">Tools and Supplies<\/h2>\n<ul>\n<li>PVC 90-degree 1-inch angle stock ($21.08\/6-foot length; <a href=\"https:\/\/www.grainger.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">grainger.com<\/a>)<\/li>\n<li>2-foot-long piece of \u00adtwo-by-six hardwood lumber<\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jmdazvkk53rd7pf2xwt8azph\" target=\"_blank\" rel=\"noreferrer noopener\">Jig saw<\/a> or <a href=\"https:\/\/outclick.co\/l\/01jmdb17r2ycnnpmdchddeenkq\" target=\"_blank\" rel=\"noreferrer noopener\">coping saw<\/a>\n<\/li>\n<li>Scrap cardboard and \u00admasking tape<\/li>\n<li>Pencil or marker<\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jmdb26e0wrq7501g65hdxkr6\" target=\"_blank\" rel=\"noreferrer noopener\">Heavy-duty scissors<\/a> and \u00ad<a href=\"https:\/\/outclick.co\/l\/01jmdb32p2gak3ndr0a4bhbnfq\" target=\"_blank\" rel=\"noreferrer noopener\">razor cutter<\/a>\n<\/li>\n<li>Assorted vises and clamps<\/li>\n<li><a href=\"https:\/\/outclick.co\/l\/01jmdb4md4wm1qw5hz9b2wk1e8\" target=\"_blank\" rel=\"noreferrer noopener\">Heat-resistant gloves<\/a><\/li>\n<li><a href=\"https:\/\/outclick.co\/l\/01jmdb5zxzfxmmm6863932hn4s\" target=\"_blank\" rel=\"noreferrer noopener\">Heat gun<\/a><\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jmdb6qfbb1d8gv5fbwqky0pf\" target=\"_blank\" rel=\"noreferrer noopener\">Miter box<\/a> and <a href=\"https:\/\/outclick.co\/l\/01jmdbamxrx4m3ye7w11zncs12\" target=\"_blank\" rel=\"noreferrer noopener\">fine-tooth back\u00a0saw<\/a>\n<\/li>\n<li><a href=\"https:\/\/outclick.co\/l\/01jmdbg65hqevpes31df383f61\" target=\"_blank\" rel=\"noreferrer noopener\">Bastard file<\/a><\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jd5chj1ykpkmpvv568z84s7m\" target=\"_blank\" rel=\"noreferrer noopener\">Power drill<\/a> and bit set<\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jmdbf9h6dkhxw0b60w6p9nes\" target=\"_blank\" rel=\"noreferrer noopener\">No. 10 Phillips 3\/4-inch-long<\/a> truss-head self-tapping screws\u00a0<\/li>\n<li><a href=\"https:\/\/outclick.co\/l\/01jaak1yeyv39x2355h7ep2gz0\" target=\"_blank\" rel=\"noopener\">Phillips screwdriver<\/a><\/li>\n<li><a href=\"https:\/\/outclick.co\/l\/01jmdbhpdtbgjc87hc9sakveq0\" target=\"_blank\" rel=\"noreferrer noopener\">Marine sealant<\/a><\/li>\n<li>\n<a href=\"https:\/\/outclick.co\/l\/01jmdbjfkg9mmkgk2mj6c1m2wx\" target=\"_blank\" rel=\"noreferrer noopener\">Shop rags<\/a> (to wipe away \u00adexcess sealant)<\/li>\n<\/ul>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-2-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Creating a template\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-2-1024x768.jpg 1024w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-2-300x225.jpg 300w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-2-768x576.jpg 768w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-2.jpg 1376w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">If possible, use the old trim as a template.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Jim Hatch<\/span><\/p>\n<\/figcaption><\/section>\n<h2 class=\"wp-block-heading\">Create a Template<\/h2>\n<p>If you have not done so already, remove the old trim.

If the old trim is not usable for this purpose, securely tape a piece of cardboard against the outside of the transom, then with a pencil or marker, carefully trace along the curve of the transom. Then remove the cardboard and cut carefully with pair of scissors or a razor cutter with a fresh blade along the line you traced. This piece of cardboard will serve as your template for building a jig to shape an inside curve in the PVC stock.\u00a0<\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Building a jig\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3-1024x768.jpg 1024w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3-300x225.jpg 300w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3-768x576.jpg 768w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3-1536x1152.jpg 1536w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-3.jpg 1689w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Creating a jig will make the job much easier.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Jim Hatch<\/span><\/p>\n<\/figcaption><\/section>\n<h2 class=\"wp-block-heading\">Build a Jig<\/h2>\n<p>I used a piece of two-by-six hardwood lumber about 2 feet in length to build the jig. Using the template, trace the radius of the curve so that it carries from the top edge of the wood to merge with the end of the piece of lumber. Next, use a jig saw or coping saw to cut carefully along the line that you drew, ensuring that the cut is as perpendicular as possible to the broad side of the board, thus creating a flat surface on the narrow edge for clamping and \u00adbending the PVC 90-degree angle stock. If not, you might have to sand the narrow edge of lumber to obtain a flat and level surface after the cut.\u00a0<\/p>\n<p><strong>Tip:<\/strong> Depending on the radius of the curve you need to create, you can use a two-by-four (for a smaller radius than in this project) or a two-by-ten (for a larger radius) to build the jig.<\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Heating and bending trim\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4-1024x768.jpg 1024w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4-300x225.jpg 300w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4-768x576.jpg 768w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4-1536x1152.jpg 1536w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-4.jpg 1703w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Using the right amount of heat will help with bending the boat trim. <\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Jim Hatch<\/span><\/p>\n<\/figcaption><\/section>\n<h2 class=\"wp-block-heading\">Heat and Bend<\/h2>\n<p>Lock the jig into a vice with the broad side vertical and the curved portion on top and hanging over the edge of your work surface to allow the heated PVC to bend around the end of the board. Clamp one side of the PVC angle stock to the top of the jig so that the \u00adother side of stock is \u00adoriented upward (to accommodate the inside curve). Gently and slowly warm the PVC in the area of the bend with a heat gun. Keep moving the heat gun to avoid overheating or crinkling of the plastic. As it softens, guide the stock carefully around the radius of the curve until you have created the desired bend.<\/p>\n<p><strong>Tip:<\/strong> A pair of heat-resistant gloves allows you to shape the curve of the heated plastic without suffering any burns to your hands.\u00a0<\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Cutting the trim to fit\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-1024x768.jpg 1024w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-300x225.jpg 300w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-768x576.jpg 768w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-1536x1152.jpg 1536w, https:\/\/www.boatingmag.com\/uploads\/2025\/02\/BTG225-WWK-Boat-Trim-5-2048x1536.jpg 2048w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Cut the trim to the right length using a miter box.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Jim Hatch<\/span><\/p>\n<\/figcaption><\/section>\n<h2 class=\"wp-block-heading\">Fit and Trim<\/h2>\n<p>Let the angle stock completely cool with the clamps in place until the PVC angle stock becomes rigid again.
