there is/was no wood "plugs" - there's 3/4" marine ply that's been in
there for 26 years - and why would a ring of 6 holes expand?

turns out West says their 410 additive can expand - they now say use
only 407.

Are you sure that sanding addiative/filler was a West product?? It sure
sounds like Talc and if it is Talc, then it is absorbing moisture..

Talc is what is used in auto body filler.

OK. I and one other posted saying that the sanding may be the problem.
OOI, can we hear back what happens with the non-expanding filler?

We may be wrong, but we tried to help.....

WEST minifibers (or is it microfibers) contains _cotton_ fiber and this
absorbs moisture too. You must seal the sandable epoxy mix as though it
were plain wood, e.g. 2 or 3 coats of plain epoxy, then primer and paint.
Note: When I fill holes, I usually let them stay bumped up a little until
after curing, then I use a SurForm or scraper (or both) as appropriate to
bring it down flush. Sanding seems to remove material around the hole more
than it removes the filler in the hole, so I don't sand. I then coat the
whole section a couple of times (usually 3) prior to painting. Works for
me.

Just a guess from many bitter experiences. What looks "flat" in the
raw will not look flat under a smooth coat of paint. I usually either
work by feel to test flatness, or try to leave a small indentation,
and fill after the first coat as best I can. It may take a couple of
try's if you are really finicky about the result.

A year ago I moved some cockpit winches before painting the cockpit
with LP. Fiberglass boat with 3/4" ply inserts in winch areas. I
drilled out the old bolt holes to new wood and glass, filled them with
West epoxy and their easy sand additive powder - and sanded them flat.

Now they've domed up under the 2 coats of LP and the 2 part primer -
you can see where the bolt holes were/are by the circle of thin bumps.

Any ideas why the epoxy "expanded" up like this. There was lots of
time between the epoxy and the paint - several weeks.

I'm going to do additional work - so would like to rectify these bumps
- probable redrill and refill - but want to eliminate a second batch.
