POR- 15 Epoxy Putty
POR-15 provides products to the automotive repair market, including auto body repair. Their epoxy putty is intended for this market, to provide a means of filling damage, while bonding surfaces together. Unlike the other epoxy putties on our list, this one comes in two separate bars (rather than one with the two components side by side or concentric), so you have to cut them both off equally. That's actually an advantage, as it allows the unused putty to be stored longer. You can work it all the way up until the time it dries. Wetting your fingers allows you to smooth the surface, eliminating most sanding.
