As "Creepin" has been doing "Rust Reduction", I decided it was time for me too. I was scared of what I might find under the front roll bar feet. It's only been in my 79 CJ for 30 years! Driver side was the worst, but not bad at all. I guess Drivers side gets used the most, so more rust collection. I Though the passenger side was looking Bad, after lifting the foot. Turned out it was mostly Dirt. Two grinders, & wire wheels on a drill, worked well. Rust prep, cleaned again, & first coat of prime. looking Fine!
