The bumpers on my mum's 740 sedan are looking pretty shabby:
Could anyone suggest how to refinish them?
The bumpers were painted a light grey which was already peeling off when she bought the car in 1999. I attempted to refinish them myself a few years ago using K&H bumper paint. A few months later it started to peel off. I thought I'd prepped the surface well, but maybe not....
I used the same paint to redo my 940's rear bumper and only now is a small section starting to peel but it's lasted about 12 years.
The local car paint shop quoted me $650 to redo both in matte black and that's with me doing all the dismantling. I'd rather have another go myself.
What should I do to prep these bumpers before repainting them? I'd like to make sure they last a lot longer this time.
Thanks for any suggestions.
