I have thinned the clear gelcoat up to 20% with the styrene and it still leaves orange peel, I sanded and polished for seven days to get my new scimitar to look as good as it does, but I'm thinking about using a dump gun this one and brush tip it. The spec's say to only thin the gelcoat 10%, but I didn't figure it would hurt much to thin it 20% on the gold boat, but it did not produce the dazzel as the one I have now, and a lot of the mix blowed out the door.
I went to the paint store the other day to get the paint for the hull on this one, and I checked out the clear urethane Omni has now, pretty tempting to use it next time, technolegy has changes a lot in the last three years, they have some that cost almost $300 a gallon, and even a mix to suspend big flake under it, and a "lifetime" warranty, next step down cost $145 a gallon, suposed to last 8 / 10 years in any climate, that would sure save a Lot of work.
