I was recommended to use USC All-Metal by a body shop owner. I've used generic brands and they all (including All-Metal) seem to sensitive to base/activator mixing ratio. Not enough hardener and plan on removing it when it doesn't set up completely.

The All-Metal is OK to spread, but can be a pain to sand. I've used Eastwood Contour Finishing Putty (also needs hardener) and I'd rate it just a touch above All-Metal, but it's way more expensive and shouldn't be used except for very small dings.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
