Bill :Good to know
Here's the thing. When a base coat/clear coat product is used with a glow engine, all's fine until a very minor crack , chip, scratch occurs to the clear coat. Then if raw fuel comes in contact with that "breech", all hell breaks lose. Crazing beneath the clear coat and that sometimes migrates -an ugly mess. Of course, Rustoleum doesn't fit into to the base coat/clear coat category, but the Hammered finish with a clear topping just might react the same way.
As Ken and Bill report ,it appears to be a different story with gasoline contact. I'd be interested in the product paint code #( if available) from the old cans for the green Ken used and the silver Bill used.
As we know, formulas often change . If I get the product paint code #( not the bar code), I can get the formula from the Rustoleum web site and compare it to today's.
I wish someone else out there made Hammered Silver and Blue in quantities consistent with hobby needs.. Dupli-color and Eastwood don't.
