I use Eastwood's Rust encapsulator, it works really good for me. Just clean whatever you are painting really well... I would be curious though, at how much heat is retained by paintin an axle (Can't be too much. I painted my rear axle and haven't noticed any problems...)

I used some degreaser, knocked off a lot of the rust with a rust remover wheel on a drill, cleaned again, used a tack cloth and then used krylon rust tough primer and then paint. If I ever do it again I'll clear it all.


I spent some time on all the cleaning and masking/taping and spraying. Not too bad though. Looks good.

Steve, I just took some degreser and cleaned mine pretty well,(fortunatley we dont encounter rust in the south, just red mud), and then hit the frame rails and springs with a can of rustoleum black rust stop paint. this pic is after about 6 months from when I painted it.

Thats a pretty shiny clean truck! Paint looks good though.

I wish there was something we could use up north here so it would look nice and clean and new like that.

I went through this at length last year after the rear of my truck was wrecked. I spent a lot of time removing the original wax coating down to bare metal and treating it with POR 15. I used a few coats of POR15 and a couple of coats of TOP Coat as well.

You'll find it much easier to clean and paint the axle and under pinnings over the frame. The waxy coat is very tough to scrape, melt, burn, wheel, sand and get completely clean in a rapid manner. I tried everything.

Probably the best thing to do if you don't want to drive yourself crazy is to use a high quality hardening type undercoating to touch up the frame. 3M makes a pretty good product. I know this isn't what you wanted to do, but the frame isn't painted to begin with so you can't really paint it later with long term success.

a couple times a year I hi-pressure wash my truck underneath and spray the frame, axles, and front/rear diffs with flat black spray paint. Very little rust in AZ trucks, but salt is used on the roads in winter a bit.

I paint my axles, frame rails, and assorted parts underneath, once a year. I use Rustoleum black. Pressure wash first, use a wire brush to knock the loose stuff off and then paint.

Lifted trucks that aren't painted down below look tacky, IMO.
