working with <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, topside paint, bottom paint, or another marine coating. The wrong repair method can create adhesion problems, color mismatch, sanding damage, or coating failure.<\/p>\r\n<p>If the surface is <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, you may be able to restore shine with cleaning, compounding, and polishing before repainting is necessary. If the surface is painted, be more cautious with aggressive sanding or buffing because paint is usually thinner than <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> and can be damaged more easily.<\/p>\r\n<h2>Common Questions About Identifying Gelcoat or Paint<\/h2>\r\n<h3>Do all fiberglass boats have gelcoat?<\/h3>\r\n<p>Most fiberglass boats are originally built with <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> as the outer molded finish. However, a fiberglass boat may later be painted during repair, restoration, refinishing, or color changes.<\/p>\r\n<h3>Can a boat have paint over gelcoat?<\/h3>\r\n<p>Yes, many fiberglass boats have paint applied over the original <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>. This is common when the boat has been refinished, repaired, restored, or had its color changed.<\/p>\r\n<h3>How can I tell if my boat was repainted?<\/h3>\r\n<p>Look for peeling, tape lines, brush marks, roller texture, overspray, color differences in scratches, or coating edges around hardware. These signs often indicate that paint was applied over the original surface.<\/p>\r\n<h3>Does gelcoat peel like paint?<\/h3>\r\n<p><a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">Gelcoat<\/a> usually does not peel like paint. It may oxidize, fade, crack, chip, or become chalky, but peeling or flaking is more commonly associated with paint or another coating applied over the surface.<\/p>\r\n<h3>Can you polish gelcoat?<\/h3>\r\n<p>Yes, oxidized <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> can often be restored by cleaning, compounding, polishing, and waxing or sealing. This is one reason it is important to identify <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> before deciding to repaint.<\/p>\r\n<h3>Can you polish boat paint?<\/h3>\r\n<p>Some marine paints can be polished lightly, but painted surfaces are usually thinner than <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> and can be damaged by aggressive compounding or sanding. Always test a small area and follow the coating manufacturer\u2019s recommendations.<\/p>\r\n<h3>Can you apply gelcoat over paint?<\/h3>\r\n<p><a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">Gelcoat<\/a> should generally not be applied over standard boat paint unless the manufacturer specifically allows it. <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">Gelcoat<\/a> is usually applied over fiberglass, existing <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, or compatible repair materials, so paint may need to be removed first.<\/p>\r\n<h3>Can you paint over gelcoat?<\/h3>\r\n<p>Yes, you can paint over <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> if the surface is clean, dry, sound, dewaxed, sanded, and properly prepared. Some paint systems may also require primer for best adhesion and durability.<\/p>\r\n<h3>What if I cannot tell whether it is gelcoat or paint?<\/h3>\r\n<p>If you are unsure, test a small hidden area, inspect scratches and edges, review the boat\u2019s history, or ask a marine repair professional. It is better to identify the surface before choosing cleaners, compounds, sandpaper, primer, <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, or paint.<\/p>\r\n<h3>Is bottom paint the same as gelcoat?<\/h3>\r\n<p>No. Bottom paint is an antifouling coating used below the waterline to help reduce marine growth. <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">Gelcoat<\/a> is the original outer finish on many fiberglass boats. A boat can have <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> on the hull with bottom paint applied over the underwater portion.<\/p>\r\n<h2>Recommended Gelcoat and Boat Paint Supplies<\/h2>\r\n<p>Bottom Paint Store carries <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> repair products, marine topside paints, bottom paints, primers, barrier coats, polishing compounds, sandpaper, cleaners, solvents, waxes, and application supplies. The right product depends on whether your boat has original <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, marine paint, bottom paint, or a coating system applied over the original surface.<\/p>\r\n<\/div>\r\n\r\n<p>Fiberglass is what is used as the base of the boat. These are the strands underneath the <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> that you typically do not see. (unless there is a gouge!) Over the fiberglass usually <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> is applied at the factory. If the surface is scratched <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> is the same color throughout; if the surface has been painted when scratched it will show what is underneath.<\/p>\r\n\r\n\r\n\r\n<p><strong>Need a repair?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>If it is just a gouge and not penetrated all the way through the boat, then you would need to fill in the gouge with<a href=\"https:\/\/www.3m.com\/\"> 3M<\/a> premium marine filler (just one product that will work but our most popular for this use). After you have filled in the gouge and sanded it down, you would then apply the topcoat of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>. (<a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> is the top finish that you see on your entire boat.) <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">Gelcoat<\/a> is typically much thicker than a paint and is designed to protect the underlying fiberglass as well as provide a smooth shiny appearance.

This will allow you to apply enough <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> and be able to feather the surrounding area once your done. If you leave the marine filler flush, then once you apply the <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> you will have a lump on the area you are repairing (<a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> should be thick enough or it could release from repair).<\/p>\r\n\r\n\r\n\r\n<p>Here are the products that you would need.<\/p>\r\n\r\n\r\n\r\n<p><a href=\"https:\/\/www.bottompaintstore.com\/fiberglass-and-gel-coat-repair-marine-fillers-and-putty-c-13581_13591.html\">3M Premium Marine Filler<\/a><\/p>\r\n\r\n\r\n\r\n<p><a href=\"https:\/\/www.bottompaintstore.com\/fiberglass-and-gel-coat-repair-gelcoat-c-13581_13586.html\">Gelcoat<\/a> or <a href=\"https:\/\/www.bottompaintstore.com\/fiberglass-and-gel-coat-repair-gel-coat-repair-kit-and-fiberglass-repair-kit-c-13581_13594.html\" target=\"_blank\" rel=\"noreferrer noopener\" data-type=\"URL\" data-id=\"https:\/\/www.bottompaintstore.com\/fiberglass-and-gel-coat-repair-gel-coat-repair-kit-and-fiberglass-repair-kit-c-13581_13594.html\">Gelcoat repair putty<\/a><\/p>\r\n\r\n\r\n\r\n<p>The amount that you will need is dependent on the size and number of gouges.
