Thanks, Jeff. From the little digging I did, it sounds like it may be hard to find these days. Rustoleum bought them out a few years ago and it looks like they stopped selling DeRusto in the US. I'll keep my eyes peeled - from what I read, there's nothing on the market quite like it for bonding to bare metal.
Speaking of hard to find, I got a kick out of seeing the Jolly release during your slideshow. His son Chris (Jolly II) is a friend of mine and he's been a big help to a new troller.
