Re: Using ON OFF on Awlgrip
On & Off instructions clearly state "For use on fiberglass only. Not for use on metals or painted surfaces".
No doubt, amazing stuff! I just used it for the first time. Takes the mustache off immediately. It also removes any wax too, and leaves the finish dull. Maybe it would affect a painted surface the same?
I'm tempted to try it on our PVC dinghy.
