why bother, either remove them completly for a smoother look, or buy some black ones (from a 1.2) and use them instead, they just stick on, easy to remove and fit as well, and not too costly, both sides will cost you £20, it will cost you that or more to have them sprayed up somewhere anyway.

WHY ARE U GONNA PAINT THEM ON THE CAR??????
IF SO MAKE SURE YOUR MASKIN UP IS GOOD AN U PAINT IN A GARAGE I DID MINE WITH A COMPRESSER I GOT THE BIG BUMPSPRIPS THO NOT SMALL REDS ONES AN MINE HAVE BEEN ON FOR 2 YEARS AN PAINT NOT COME OFF YET JUST
PRIME RUB DOWN PRIME RUB DOWN PRIME THEN PAINT THEN LACQUER USE A GOOD LACQUER, I HAVE FOUND THE BEST COLOUR MATCH IS TO GO TO VAUXHALL AN BUY SPRAY CANS AS IT COMES WITH LACQUER AN THERE LACQUER IS GOOD

I want to get the red bump-strips to black. What's the best way to go about this and will I have any problems...e.g...paint flaking off??

Cheers!
