Optimum Gelcoat Restorer (GCR) brings heavily oxidised and faded gelcoat back to a factory fresh gloss without polishing, sanding or compounds. Engineered for boats, yachts, jet skis and RVs, GCR soaks into porous, sun damaged gelcoat and rebuilds it from the inside, restoring colour and adding UV protection that lasts 2 to 3 years. One 946ml bottle covers up to four coats on a 40ft boat.
Detailing Shed is the Australian Master Distributor for Optimum Polymer Technologies. Genuine product, authorised supply, full local support.
Yes. GCR works on both clear and coloured gelcoat, provided the surface is sufficiently oxidised and porous to absorb the product. It restores the original colour by re saturating the pigment.
Polishes and compounds remove gelcoat. They grind the oxidised top layer away to expose fresher material underneath, and each pass takes a tiny bit of your finite gelcoat thickness with it. GCR works the opposite way. It absorbs into the porous oxidised layer and rebuilds it from the inside, preserving the gelcoat thickness while restoring gloss and adding UV protection.
2 to 3 years on most surfaces, provided you maintain it by washing with Optimum No Rinse and applying Optimum Car Wax every 6 months.
No. New gelcoat isn't porous enough to accept GCR, so the product won't absorb properly. GCR is specifically engineered for old, sun damaged, oxidised gelcoat. For newer surfaces, use a maintenance wax or marine sealant instead.
Anywhere from 1 to 5 coats depending on the level of oxidation. Light oxidation may only need 2 to 3 coats. Heavily oxidised, chalky gelcoat typically needs 4 to 5 thin coats. Gloss really starts to develop on layers 4 and 5.
Yes. Unlike most polishes and waxes that need shade and a cool surface, GCR can be applied in bright sunlight, which makes it practical for marina and outdoor application where shade isn't always available.
Streaking usually means too much product was applied. To remove it, polish with Optimum Hyper Polish and an orange foam polishing pad. For stubborn streaks, step up to Optimum Intensive Polish.
