Rust control

Post by mpg » Tue Dec 30, 2014 8:32 am

I'm still a ways off from a full restoration
Is there anyway to halt rust on the underside of the jeep body until then?
Apply something that can be sandblasted off later?

On my frame while I gather the funds to sandblast/weld it, I used a wirewheel to break off the loose rust I could get to and used a rust converting primer on it. It's been a few months now and it still looks good. It may have not stopped the rusting completely but I sure hope it slowed it a little :D

He said he wants to be able to take it off later!!! :lol:

To contribute: hit the rust spot with the wire brush and then use some rustoleum on it. That's what I've done on my jeep body while it sits.

Like ez8 said, wire brush or wire wheel the big stuff off and hit it with some Rustoleum rusty metal primer. If you want to go the extra step, consider using some Rust-Mort as well, it's mostly phosphoric acid which will convert the rust. Then paint on the Rustoleum.

What part of the world do you live in? Here in Colorado, it is very dry air. Sandblasted parts can sit in a shop for years and still be rust free. If you store something outside, do not tarp it. That makes a sauna to keep the heat and moisture trapped. It's best to build a tent over it and let the air move. If your tarp is less than 6" off the jeep, there is too much trapped moisture. It should have open ends so air can flow easy but keep rain/snow out. I like hitting all rusty areas with phosphoric acid to convert it. The converted rust will slow the process of rusting and is easy to sandblast off. What does not come off will be fine under paint.

To prevent further rust until you can treat it in the future ACF50 is a good product designed for this purpose, just spray it on and away you go
