I am trying to paint my fiberglass boat with Perfection (from Interlux) my hull (topside).I selected Flag Blue. I have also bought the primer and all the solvents.I just started the first step which is sanding with 220 and now I am getting ready to apply the primer. The only thing that I am REALLY concerned is...Should I go by roll and tip off or maybe I should go by spraying. I am better than average with painting but have little experience with spraying. SO... You can probably understand my position. A lot of times the factory will say one thing and when the average Joe does it, is a lot different. Did anyone go with the tip off way and had any good results?Anything that I should be aware...I watched the movies at Interlux (Perfection application) and it does not look very difficult. I am concerned about the surface being glossy enough and obviously with no streaks.Thank you so much.Daniel
