grey bumpers best fix?

[Stick Legs]

Hi, p38a range rover with blotchy grey bumpers, I have seen a couple of products which claim to dye it back, Wurth do one for about £35 and Autoglym for less than half that. Anyone got any experience or tips, or is the best course of action to dye them at all! Cheers.

Excellent idea, used the hot air gun followed by lashings of AutoGlym Bumper care.
The results are amazing. Thanks guys! Will post a pic shortly.
