I'm working on the fairly extensive battery rust, caused by the bad tray design. Who thought

rolling a battery tray lip down over a structural part was a smart idea? Oh well, just thought I share the fun

with you guys. Enjoy? https://www.nopistons.com/forums/pub...DIR#>/ohmy.png ,,,,BB

https://www.nopistons.com/forums/pub...1047683572.gif Thats extensive.Get out some 16 guage steel and a welder and goto town.And people here ask me why I like to relocate the battery.

Only real rust on the whole car, go figure it would be so bad, huh? I got some 14 gauge angle to bulk up the top of the frame rail. I already cut off the piece that stands up straight off the rail, and the angle will replace that. I have a sheet of the lighter gauge that forms the inner fender, to fill in. Once this is overwith, I am building a battery tray out of 16 gauge, with a 1 inch lip all the way around, and a drain to outside of the car. The tray will be powdercoated as thick as they can possibly do it. I don't want to do this again.,,,,BB

Took a day off, and got back on it today. Got the rail piece made. Easy. Made some pie cuts in the angle, bent it to follow the rail, then weld and grind it off. Looks pretty spiffy, hehe. Now I have to find a way to de surface rust the rail, so the welder will do it's job. I only have a blast cabinet, and the cars a little too big for it. I guess I could fit the grinder in there somehow??,,,,BB

I use a Makita 4.5" grinder with a wire wheel to clean up bad ares like that.Then use a good rust primer and paint.

I was able to get my air grinder in there, and got it clean enough to give good penetration. Makita wire wheel would've been my first choice, but it would not fit with

the T handle installed. About 10-12 years ago I had a Makita jump out of a two handed

grip, almost slashing my left wrist open, pinch bruising my leg through blue jeans, and then hit the ground, only turning off when the wheel caught the power cord. Since then I NEVER remove the T handle, lol. An experienced coworker had removed it. I found it, and installed it with a wrench, hehe.,,,,BB
