On VC-17, I've not applied it myself, but have observed the application to my boat several times. A solvent resistant roller was used. It seems quite thin, and only a small amount was mixed at a time. No thinner was used. Six, less than one quart cans were used on our 36' boat for more than one coat, which I think is somewhat more than usual. It dries quicky so there was no wait between coats. Extra coats were applied to leading edges.
