I have not found any study with closed cell foam contributing to accelerated rust. It is used a good bit by industry, the new Jeeps use foam in the cab and roof to help sound proof, so if you own a monkey/new jeep may be worth studying. Pretty easy to test the idea with a couple of sections of...

Thanks, Right now I guess the solution is to insure drain holes are not plugged or drill the frames where they don't exist.

I filled a frame with close cell foam back when I worked for the Corps. From a strength and stiffness perspective it works. Foam will go up to 40 lb/ft ^3. Even at 10 lb/ft^3 we saw significant improvements. Reading the reply's I understand some of the concerns and will test for it...

what if it is an old jeep that has all the issues of rust in the frame. If you could dry the inside of the frame, I dont think I can get the rust out, I would think it would degrade rust. I might run some tests to prove or disprove the theory. The increase in strength with just 8...

Why, I have run tests that prove a significant increase in strength and stiffness. I don't sale the product, just a researcher.

Do you have any test data or links to support the statement

Has anyone heard of Foam stuffing for the frame to prevent rust and increase strength.
