The Bondo Thread


Well-Known Member
I s there anything it can't do? The only problem I have with it is that there is always a sticky lair after it cures. Why does it do this?
mine always ends up a tad tacky as well but as soon as I hit sandpaper to it, it mysteriously disappears :) It could be due to humidity or as Contec mentioned not enough hardener.

The tacky problem is moisture that's causing that problem, as for trekman's problem not enough hardener. I would usually mix a batch on a piece of cardboard and the pile of bondo on the cardboard I put a strip across the top from one end to the other and it's usually the perfect amount.
