so far ive had success with satin finish smoothrite in aerosols... i spent a long, long time keying up the side trim though, im happy that it will last, i dropped one section onto the road as i was fitting it up (foool!!) and it just bounced, no scratches or anything! ...not so sure how im gonna do the rear bumper though, the only decnt one i have is chromed, and keying it up is gonna be tough! front bumper is sorted already though, i have one from a jeans beetle thats already satin black.. its a bit scratched though, so ill blow it over.. before i fit it i intend to weld some kind of home brewed steel chin spoiler to it. im either going to cut sections from a scrap bonnet to make a sculptured spoiler, or ill just weld some flat sheet under it that will follow the curve of the bumper with a small plastic trim from a scrap modern car at the bottom... the latter seems easy option right now!
dont tell me youve caught the carbon fibre bug too????!!!!
