I, a dummy, feel dumb asking this:
Since I am doing body work-
"What's the finished difference between using 3M Ultrapro Autobody Sealant
(tan or clear) and bondo?"
I know the 3M stuff comes in a caulking tube or squeeze tube, bondo has to be
properly mixed. Bondo dries much quicker. Bondo is cheaper. While I also
know that the sealant is applied to a crack or hole, can't bondo do this?
What I don't know is which is stronger or less likely to be waterproof? Is 3M
superior on rust? Is there some other distinquishing feature of one over the
other?
Thanks, Paul Dorsey
