While waiting on my new wheels and tires I decided to clean and paint the suspension and wheel wells. It's something I've been meaning to do but have been to lazy. Selling my old wheels motivated me to get to work
When I did mine, I say it was close to 5 lbs. of grime from front to back that I removed. I had to use a putty knife to scrape off the crap that accumulated from the floor pan back to the storage bins. It was especially bad near the diff.
