Hello, my first post in the forum. Last summer we discovered (when the skid plate almost ripped out of the frame at Dirty Turtle, KY) MASSIVE rust damage on my wife's TJ. After some research we went with Auto Rust Technicians full frame rail kit, both sides. After many hours, cutoff wheels, flapper wheels, and cheap Harbor Freight flux core welder (converted to DC output) it has been solid thru many many off-road and highway trips. Very happy with the results; prep is key! DROP THE TANK. Cut out the bad, clean up what's left, and weld. Lots of work but had it all done in 3 days.
