TeeItHi

as most of you know testpipes leaves brown exhaust stains in the rear bumper around the exhaust tips... so i was cleaning my car yesterday and i noticed some small rust dots around the doors and rear bumper (i don't get to clean my car much doing winter and didn't noticed these last time),i've had my non res testpipes in since june. i was able to buff some out but not all my have to use other type wax or clay bar... does anyone know if these are cause by the testpipes as well?
thanks

I also have a white G and noticed small rust looking dots on the side of the car,near the rear. I used Meguiars light to medium compund and Meguiars paste wax to remove these dots, as long as its not an actual chip through the clear coat and base coat this should remove the spots. As far as the test pipes go it is very possible with the higher flow and no restriction that your getting blow bye, from the internals of the pipe or res test pipes.(carbs) On past cars ive had the same issue though,just had to pay more attention when cleaning and spend more time in these problem areas. good luck to ya

2009 white G and I get the same small rust spots from behind the front tires. They are the worst on the trunk below the spoiler. I haven't gotten mine taken care of yet but I hear a good wax and clay does the trick.

I was not aware of TP's leaving a brown stain, may be cause my G is OB. Interesting though.

Ive had test pipes on my IP for almost 2 years now. Never noticed anything on my bumper...ever.

I think what you guys might be referring to are iron deposits from road grime and other airborne deposits. Use an iron cut like aquartz and it should take it right off. no need to whip out the ROP
