Does anyone know what brand or manufacturer of undercoating matches the factory finish on the frame? I have to do some touch-up and I would like it to blend perfectly. I called my local dealer and he just referred me to the auto parts store. The auto parts store could not tell me either. Thanks, Bob

I was told it is Nox Rust X-121B.

Find a post by hoot. Check his sig for the link to gmc trucks. He has it in there.

It's a Hot wax dip.

Towin43 is correct. There's a company I think in Chicago that will sell aerosal cans of the stuff for about $7.00 a can.

Thanks for the info. I called the company that makes the Nox Rust X-121B and they could not refer me to anyone that sells it retail. I also e-mailed Hoot and he did not know. Does anyone know the name of the place in Chicago or anyone that sells it retail by the can? Thanks, Bob

I just sprayed some flat black high heat paint on it. It will look like it was touched up for the first 2 weeks, but after that it will blend in with the color.

But no matter what u use, u will still be able to tell a little bit its been redone.

I found the information, I just didn't want to link to a search criteria.

Here it is:

If that is what you already tried, I'll keep digging.

I just found the distributer.

Thanks a lot Dave! The posting with the distributor named A.M.A. still sells the Nox-Rust for $6.00 a can w/ a (2) can minumum purchase.
