Sup fellas, one of your own w&w Wackos needs some help. I recently added a Berk Testpipe to my Fuji Dual exhaust. the problem im having is that since my car is white and i dont have a cat now, the rear bumper around the exhaust is starting to turn yellow a bit. i try to keep up with it as much as possible using Klasse AIO by hand. it seems to work some, but not 100%. does anybody reccomend using another product to get my rear bumper back to its bright white?

 

clay bar it and rewax it. im sure wannabe or someone else has a better solution though.

 

importkid- i am with you... first step would be clay. if the stains are new clay will usually do it.
if the stains have set at all, you will need a polish. try a paint cleaner or swirl remover first. or sometimes a bug & tar remover will get it (i would first give that a try in a small area- i like autoglym's product). so do the bug & tar remover first then go for the polish if you need to-
if that doesnt get it, then you would go more aggressive- but you really shouldnt usually have to.
report back!!

btw, prevention is the key here- once you get her cleaned up, be sure to rewax. then after driving, i use a duster that i only use on the lower parts of the car (wheels and exhaust areas). after dusting, use a detailers spray (my preference for this is for carnuba based sprays- but thats a personal pref) to get any left over residue. this should keep the car looking new and keep the exhaust from adhering to the bumper.

 

thanks wannabe! i will give my claybar a shot tomorrow afternoon! i will report back with my results after a re-wax.

 

ok, heres what i did: (just to the rear bumper)

Dawn wash
Claybar (took a lot of the yellow out)
Klasse AIO x2
Klasse SG
S100 Carnuba Wax

Looks a whole lot better! Thanks fellas!
