Hi, iv just got a set of phase 1 bumpers for my pearl 5, now under neath they look good with no scuffs or marks, but they have had a coat of paint, no primer just one coat of paint which has fell off in places anyway, does anyone know what I can use to get the rest off? don't want to use thinners in case it melts the plastic! going to try a jet wash tonight, but suggestion s or experience would be a help, cheers
