Well heres the thing,the white trim is not paint it is white color fabric, I cut it with a razor and straightedge,and this is why I need to clear over it.Awhile back I patched a trainer with some white 21st century fabric and the glowfuel turned the white fabric pink,I don't want my astrohog turning pink so this is why I wanna clear it,also I don't wanna see my trim blow off the plane.If u do want sharp lines go to the automotive shop and get some pinstripe and use that as your mask where your stripes will be then use paper and regular masking tape to cover the rest,start out with very light coats and allow dry time between coats.remember to that the thicker the pinstripe the less it will bend,so if you want to mask off something round use thinner pinstrip.Ok back to the clearcoat I was trying to stay with something in a rattlecan just to make it easy,now if I did go with something to spray from a gun what about clear gloss dope? It's cheap and fuelproof,any Ideas on that?
