Pick up my new toy wednesday, its a mk3 golf cabrio! anyway bumper trims have gone grey! whats the best way to get them black again!? many thanks
never tried it myself have always used back to black but, the wax not spray. Might try the boot polish technique on my punto bumpers.Peanut butter! yes i didnt believe it till i saw in on discovery turbo wrecks to richs, the oil in the peanut butter restores the colour and they say it last longer then any other product. It seemed to work well on there car not had chance yet to try it on mine.
I Watched the same program looks good dont dare try it tho. but seemed to work well 
Someone told me that parade boot polish works quite wellnever tried it myself have always used back to black but, the wax not spray. Might try the boot polish technique on my punto bumpers.
if you really want them to go black pemanatly use a heat gun dont get too close and take your time and they will look like brand new
