I'm having to strip my 3dr's front bumper right back (its had many many paint jobs in the past and its now built up so much that its cracking in places, also the second paint job it had looks like its not took properly and has lifted...so bare plastic seems the only answer), I've been working away with W&D 180 for most of the morning and seem to be getting no where at any pace. Is there anything availble that will safely strip off the paint yet not harm the plastic or cause problems when it come's to the repaint?

Cheers,
Stu.
