Yeah I did roll and tip 2 pack and I had enough time to paint the boat in one go. I was expecting to use 500ml on the first coat and have 800ml left for the last coat but only used about 350ml so Im guessing I will have 2 more coats and sand it lightly between coats. I hope it turns out well. Has anyone had waterline done on Laser? Whats the easiest way to paint it?
