In respect to this, how long should Bondo cure before sanding?

Generally, in a matter if a few minutes it will start to harden and get rubbery. At that point, you can carve it up with a utility knife, a hand planer or a bondo rasp. Just make sure you leave enough to do a final sanding, usually within 10 to 15 minutes you can start sanding it.

Also Know, why is my Bondo not drying? If the Bondo isn't dry, it's because you didn't use enough hardener or the temperature is too low. Getting it wet didn't help. Try using a heat and strip gun. It gets hot pretty quick so keep it moving.

Also Know, how long does it take for body filler to cure?

If your filler hardens too fast, you used too much, if it takes too long, you didn't use enough. You only want to mix what you can use in about 10 minutes. Properly mixed, body filler will begin to thicken in 10-15 minutes, and be fully cured in 30.

What happens if Bondo gets wet?

If you got some bondo wet and then dried it out, you could grind it down and it wouldn't have any moisture inside, but the metal behind it may have already been oxidized and then you'll have problems.
