My bumpers were faded and grey… I heard a rumor that a heat gun can bring them back to life. Turns out it was right….
This is the heat gun I used…
I timidly tried it on a very small area…. and started off trying to mask off the paint work with a bit of ply…. by the end I was just wafting the heat gun around. You have to hold it in one place longer than it takes to get the colour back before it does anything to the paint.
….just wash your bumpers first, I managed to burn some moss on mine!!
Update….
They went grey again disappointingly fast, maybe repainting or oiling is the way to go.
