Teardrops n Tiny Travel Trailers

I've heard many mentions about Bulldog Adhesion Promoter; however, have not been able to locate it. Can those who've used it tell me if any "national" store carries it.. HD, Lowes, Autozone, etc., etc... I etched the aluminum w/ vinegar lastnight from what my G'pa said could be done when we were growing up, but don't know if that's for sure true or not.

Keith....it's primarily for professional use...you need to go to an automotive paint supplier to get it, big box stores aren't going to have it...Doug

Thanks Doug. I think we have one here in town somewhere, I'll give 'em a ring.
