The mix sprays like paint and cures to a smooth, hard, glossy surface with no surfacing wax and no PVA over the top.\u003c\/p\u003e\n\u003cp\u003eIt is the fix for the dull, low-gloss ring that shows around the edge of a gelcoat repair, and it lays down flatter than straight gelcoat or gelcoat cut with wax and styrene. Use it for gelcoat repair, full gelcoat resurfacing, and plug and pattern work. Blended into tooling gelcoat at 10 to 25%, it improves flow and air release for a mold surface with less porosity.\u003c\/p\u003e\n\u003cp\u003eBlend 1 part additive to 1 part \u003ca href=\"\/collections\/gelcoats\"\u003egelcoat\u003c\/a\u003e for repairs where color hide is not an issue, or 1 part additive to 3 parts gelcoat when you need the most hide. With dark, rich colors, spray the build coats in straight gelcoat and finish with the 1 to 1 blend. Catalyze the whole blend at 2% MEKP. The surface is sandable in roughly 2 to 4 hours. Leave it open for 8 hours after the first sanding, then work up through 400, 600, 800 and 1000 grit and polish.\u003c\/p\u003e\n\u003cp\u003eIt works with most gelcoats, but every gelcoat cures a little differently, so run a small test blend before the real job. Keep the shop and the part above 64 F. It can be used anywhere gelcoat is used. Where the surface will sit in the water long term, finish with the 1 to 1 blend for the last 10 mil or more so the surface cures closed.\u003c\/p\u003e\n\u003cp\u003eBoth sizes ship with MEKP catalyst.\u003c\/p\u003e","brand":"Duratec","offers":[{"title":"Quart with Catalyst","offer_id":68005546164526,"sku":"DURA-904Q","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Gallon with Catalyst","offer_id":68005546197294,"sku":"DURA-904G","price":194.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/4071\/2494\/files\/duratec-904-001-clear-hi-gloss-additive-gallon.jpg?v=1794440454","url":"https:\/\/boatsuppliers.com\/products\/duratec-clear-hi-gloss-additive","provider":"Boat Suppliers","version":"1.0","type":"link"}
