i took my whole kit off and then masked it all off, well almost, got a little overspray in places but tcut it off. i just sprayed the strips but had to spray one panel do to some heavy scratches i had to sand out.
im going to get another set of arches and side panels and spray the whole things as there are a couple of bits where you can notice the difference slightly but the one panel i sprayed fully looks good
hers is what i did, it looks rough in pics cos i hadnt flattened and buffed them up, i did mine with aerosols aswell as im on a tight budget lol
