White Gelcoat (Quart)

Really good gelcoat; I used a 2.5mm nozzle and a bit of thinner, about 1oz/pint of gelcoat. Watch the hardner, the label says at 75F use 78-82 DROPS of hardner per 4oz of gelcoat, do NOT transpose that into 320 drops per 16oz or you will have a 16oz white hammer head, and with thinner it will go to about 200F and actually boil - no bueno. Get a 5ML measuring glass tube and measure hardner carefully, check out Totalboat website too. MORE!!! On my 17'6" Whaler I used too little of this; I would say use 8-10 qts [depending on what you want and what you are covering] for this size boat. Reasoning; You must put coating ON to take coating OFF, to smooth, sand down using 1000 grit or 1200 grit to get that mirror finish. If there's too thin a coating, you'll be taking it ALL OFF [like a girl named Susan that I used to know] and never get it as smooth-mirror-like.

Great product, very easy to apply to the hull as a final coat. This gelcoat is much easier to work with around 70-80*. I used a 1/4 inch nap, no lint roller to apply the gelcoat. Now it’s time to sand and buff.

This product is thin almost like paint so it will take time to get a buildup on the bottom of a boat ,but I am very pleased with the results. I especially like the catalyst it is liquid and you can get precise ratios one drop at a time.

Easy to apply and stays on well.

I had some deep scratches on my gelcoat layer of my fiberglass Casita RV I wanted fixed. This seemed to be the right product for the job. Mixing with reactant is a critical step and the directions are very complicated to get the right dose. I ended up with not enough catalyst in my mix and it took days to dry, in Texas. It does do the job, but it is tricky to apply because it's like a very thin paint and gets quite messy. The white is white, which doesn't exactly blend in with the Castia's off-white color, but I mostly needed for my wheel well so it's not very noticeable. Wanted to use it in other places, too, but I don't think it would look good.
