Is there anything you can do that will make it impossible for the exhaust fumes from baking into the paint? Its like hell every time I go to wash off the rear of my car if I have even gone 3 days without wiping it off!

with FI and more fuel it obviously compounds the problem!!! Is there any protective coating or sealant that prevents that residue from literally BAKING onto the paint??????

 

common problem even with stock exhaust... and stock wheels

with upgrades it gets worse-

i use a duster probably every other time i drive or so on the rear of the car, then follow with a detail spray. i like detail sprays with either synthetic or wax in them- they seem to help reduce the stuff from sticking as much.

for you the first step is to wash and then clay - then coupla coats of synthetic, and i would end up with one coat of wax.
after that, duster and detail spray as needed.

pia, but its just part of my driving routine now- when the car come in the garage i glance to see if it needs dusting...

 

Great advice!

I would just add not to get too far behind on it. I've found that there are thresholds where you can often get it off with detail spray, a little longer takes washing, and ultimately it takes clay or a cleaner/wax to remove it.

 

Try some Colline 476S. It's the most durable sealant I've used, and sheds dirt better than anything else I've tried so far
