Thank you all for your comments.

For the record, I ended up thinning it about 20% with alcohol. This worked
well as far as thinning is concerned, but the alcohol apparently evaporates
too fast. It is impossible for the brush strokes to flow out well. So --
more sanding. The good news is that it finds, and with persistence, fills --
or at least coats -- about every pin hole in the resin base. It dries
quickly and appears to sand well. I am actually using it as a primer under
Interprotect 2000 BTW.

This is the second time I have purchased Interlux products which have been
described as applicable to things I later found out they were not truly
suitable for.

Just for the record, Jim, the can is labeled Epoxy Barrier-Kote. And the
catalog describes is as suitable for above or below water applications.
The directions also state that it must be thinned.

Thanks for your thoughts.

Interlux 404/414 is not a barrier coat. It's a sandable primer whose
function is to provide a tie coat between sime substrate and an
impervious
finish coat such as an LPU paint. If applied as directed, it's just
loaded
with expensive solvents and is consequently pretty porous. Useless under
bottom paint. If you are using it as a primer under finish paint and
not
under bottom paint, go for it. I'd try acetone. Let us know your
result.

Can I successfully use acetone to thin epoxy barrier coats? I am
thinking
of
Interlux 404/414 in particular, but the question is also a general one.

I am aware that there are proprietary products for this application, but
I
need to paint tomorrow morning, and the nearest dealer is about 60 miles
away.
