I've got a couple of corners on my fiberglass CC boat transom that have been
smacked around during docking or something. Both corners are skinned.

I need to make a repair with compound contours. What's the best way to get
a smooth surface with bondo so it minimizes shaping with a rotary file or
grinder? Does working it with a wet wood paddle minimize cling and stick
and give me a reasonably smooth surface to work on?

Do not know if Bondo is good for your repair. But to work Bondo, use a rasp
/ micro plane type shaping tool, while the Bondo is still semi soft. After
it first hardens, it is easy to work. Later it gets to the point of needing
a grinder and sander, but will be the consistency of Cheddar cheese for
awhile.

I'm not sure about Bondo, but I've used fiberglass and resin sandwiches made up
on Saran Wrap to patch a few times. Just make up the patch, stick it on and
mold it with your fingers. After it sets, the Saran peels off and leaves a
smooth surface. You may have to watch it for awhile until the resin "goes off"
to prevent running out.
