Por 15

[Squirrelsmith]

I am considering going to town on anything i can reach with a paint brush. Everything underneath has a nice light rust color to it. No heavy rust just surface.
Anyone done this?

Type in Por 15 in the search field and there are many threads dealing with this product and other thoughts on undercarriage rust and coating(s). Be worth digging through those threads for ideas, as there are so many threads, etc....
