TremPro 635 Melting?

I'm working on a 1974 international. I sealed the exterior with TremPro in the past. Now that I am trying to polish it; I am having major problems with the TremPro melting and smearing around on the metal. It turns black and leaves a mess that I cant get off. Sometimes it is so thick it forms a hard crust that will chip off.

I tried 1000 grit sand paper on a buffing wheel and it clears it off for about the first second of contact then the paper is contaminated and smears it all around again.

Goof off does not do anything.

If you canít wipe it off with a solvent, the black may just be oxidized aluminum and you need to keep polishing.
