is it possible to do a good repaint on a boat trailer without taking it to a sand blaster? the trailer under my winner is starting to look rough and have been thinking about wanting to clean it up again. fresh paint, replace the wiring and the boards. i know the trailer has atleast two coats of paint. there's been a coat of black brushed on by the previous owner but it appears the original color was gold. any thoughts on doing the job right without paying a sand blaster?
