Finally got a chance to work on my truck today (been raining nonstop lately). Pulled the seat, floor mat, gas tank (going to radiator shop), and door sills. Going to clean it up a bit and lay some dynamat behind the tank for now until I can get the rockers done. Then I'll sound proof whole floor and add carpet. One good thing I found is that the rust isn't any worse than I thought.
Also got some CLR and went to town on the rear fender. Very pleased with results! This is with only 15 minutes of scrubbing.
