I drilled a 1" drain hole in the bottom of each frame rail and made mini fish plates to prevent them from cracking.
Then welded a nut offset on the end of a rod, stuck it inside the frame and hooked the other side to a drill. It banged around like crazy and knocked a bunch of rust loose (My Dad's idea). I also used a needle scaler on the outside.
Then I pressure washed the inside down and pulled over a gallon of rust scales out of the frame.
After it was all cleaned out I shot 3 cans of Eastwood's internal frame coating in the frame rails. Coverage was great.
Then I wire wheeled the whole frame down and hit it with 2 coats of Chassis Saver satin black.
35 MTRs on Black Classic II, Currie front trackbar, Antirock, YJ front brake lines, Currie bumpstops, Bilstein front shocks, BDS 3" coils, Undercover Fab low profile tcase mount.
I still need to do a complete alignment on the front (control arms, trackbar, steering etc) and add another exhaust hanger.
