Well its not rocket science after all, just common sense and patience required. Thanks to those who have offered LPU advice recently on this board.
I sanded out my streaks and put down 3 more coats on the hull this morning. It looks really nice now. I started at 6am and gave up when the temp. got up to 65 deg. 50% humidity. That seems to be the point at which the stuff will not flow out before drying so that brush marks show. I also worked in 12" sections and brushed downward from the keel rather than from side to side as I had previously. Lessons learned. I will put on 2 cross linked coats tomorrow am and move on to the deck.
Thanks again for the help.
Mike
