I wood use Bondo for interior work without a second thought BUT I
would never use it again on exterior work. *YMMV.

Bondo works just fine on cars, even those that are used outdoors G

The stuff is a lot more $'s than Bondo.

Epoxy resins are simply more $$ than polyester resins. The
characteristic odor of uncured Bondo is from styrene, a reactive
diluent which makes the product even less $$. So buy whichever system
does what you really need.

Yes, Joe...Bondo works fine on cars......even those used outdoors,
just not cars made of redwood (what other woods?)

According the Bondo tech support, Bondo (at least the formulation sold
20 years ago) is not for use on redwood in exterior apps..... I wonder
if there are other species of wood for which Bondo is also "not
recommended".

The take away message from Bondo tech support was "Bondo is not good
for exterior use with redwood".

I extrapolated it to.....I don't risk using Bondo for exterior wood
repair.

Having experienced an exterior repair (of redwood) that failed, I
decided to not take that chance again......

So the only different between epoxy resin and polyester resin is cost?
