just saw an infomercial on this stuff - looks promising! i can think of 10 uses right off the top of my head for r/c's. airtight, waterproof, forms a bond to itself... and unlike electrical tape, it's resistant to heat.
My dad has been in love with stuff for a long time. We have a hardware store, he uses for all sorts of stuff. I used to temporarily fix some sprinklers last year.. Pretty cool stuff..
