just wonder on the best product for rust conversion, either sray on or brush.

i dont mind paying good money for a product that works, its just finding that product.
any info would be great
thanks

 

If the part is small enough use WHITE VINEGAR, let soak as long as necessary.
Good luck

I tried to halt some of the cancer on the crusty 85 442 a couple yrs ago. Parts store spray on converter. Common stuff, keep wet with 2-3 applications, then it turns the area black. Purplish black. I sprayed over that with common black paint. It has held up surprisingly well, but the goal was not a pretty and smooth finish, just "Not a giant brown spot amid the black of the car".
