Hi Guys
Im sure this has been asked befor but im a newbe

im pull my chasse a part in the next few week (1935 chrysler airstream) and the chasse is pitted where the body sits
it not bad (no holes) but what do you use to fix it
and what paint is best to use once its finished

thank
gary

If the pitting is indeed just cosmetic sand blast the frame and fill the pits with any good body filler. Sand smooth and prime. Paint the frame with any good chassis black, Rust-O-leum, or Por-15 type paint. If the pitting turns out to be holes and strucural weakening the services of a competant welder should be used to cut and weld in new steel...............Bob

thanks.

i had trought of body filler but trought it wood crack and full out leting it rust again

Not if you sand blast down to clean metal. If you just smear it over rust yes it will eventully fail. Blasting down to new metal is essential. The rough sand blasted surface also provides excellant "tooth" to grip the plastic filler....Bob

I usually use an epoxy primer after sandblasting and fill deep pits with a good filler or small pits with a hi-build 2K primer, then topcoat with acrylic enamel. Most cars I do are from the 20's and have exposed front and rear frame rails. If none of the frame is exposed to sunlight than POR 15 or chassis black will work fine.
