I am now fiber glassing the Dumas crockett and I am having trouble with brush marks and runs. The problem may seem obvious " use finer brush, put thinner coats on that wont run", but, I did not have this problem with some of my other jobs and starting thinking at other times I used resin from the hobby store and now I am using Home Depot resin, could the problem be that simple, thanks, Randy.
