Topic: Frame rust

[toolman]

I found a bit of rust on the frame of my 82. (No big surprise). Anyway I was cutting some of it out and I was wanting to coat the inside of the frame with POR15. Does anybody have any good ideas on how to do it?

Whithout doing a frame off rebuild I don't see how ya could possibly coat the inside of the frame completely. With a bare frame you could dip the frame in something but I still don't thing it would be cost effective, expescially on a used frame.

I see it being a waste of time. Get a new frame if you are worried about.

u could just buy a brand new frame from budbuilt lol

Well a new frame would be nice, and as soon as I find that money tree I may get one. Ha. As for the rust on my frame it's really not too bad, just one spot on the pass. side behind where the gas tank mounts. I think I'll just wash the frame out as good as I can and use a cheap bug sprayer with a hose and spray a liberal coat of the por15. May slow it down some.

Just cut the rust out and weld in new sheet metal. Use a cut off wheel and take out all the rust and weld in new. Behind the fuel tank is common. I had to patch the frame on my 92 in that spot.

Yeah I cut out a spot and patched it. Just wanted to see if anyone had any ideas for applying the por15 or some other rust preventitive in the frame. It will rust out eventually, just wanted to slow it down. I plan on welding in some 3/16 plate on the inside and out of the frame to strengthen it some so if it does get any weaker.

If you really want to slow the rust down you can attach unfinished lead chunks to your frame. Rust attacks the weakest metal first. That is why the body rusts first in most cases. In theory as long as you change the lead chunks out before they are "spent" your frame would never rust. Rust is a chemical reaction after all. This is how naval ships can float in an ocean of salt water and not rust as much as you would think.

sacrificial anode!  You'll see them on boats and boat motors, though those are usually zinc.  That's more of an electrolysis problem though.

does anyone actually do this though? I have never heard of this!  BTW it might be a good idea to fishmouth the plates if u weld them on

[toolman [OP]]

Gonna taper the ends of the plate when I weld them on.

never heard of using lead, but zinc works like a mofo
