: Good day Douglas,

: What you are experiencing is what all of us have experienced at
: some point. Most of this stuff is pretty fixable.

: See my comments embedded below:

: Not sure what you mean here, but you can sand it fair and then add
: another fill coat of varnish. If it's still showing through then
: you can sand with a very fine grit- like 1500, and that will
: often cause the fibers to not show through as bad. Usually if
: you have it showing through then you have bare fibers that just
: need more epoxy.

: Sand it, add another layer of varnish. If it's real bad then you
: can scrape it with a razor blade held about 90 degrees to the
: surface, then sand, then varnish.

: See my other comment above about sanding with 1500 grit. It worked
: for me when I had a cloth that didn't wet out well and showed
: through.

: You can do it. I'm not much for dyes, but people have done it with
: good results. Do a test first to see if it mixes with the epoxy.
: I have had some cheap dyes that lifted into the epoxy when I wet
: it out.

: Most varnishes take forever to fully cure, so you may have trouble
: wet-sanding them. You can certainly do it, but it has to fully
: cure and be hard for wet sanding to work. I would scrape first,
: then sand, then likely you have sanded beyond the varnish and
: will need another coat. I have switched to automotive clear
: coats, and I wet sand that, but varnish I usually just let it be
: as it.

: Nope! You need to sand it out. The specs of dust are likely bigger
: than a coat of varnish, and they will also impede the flow of
: the varnish. Sorry... embrace the sanding! Pretend it's your
: favorite thing to do!!! LOL

: Cheers,
: Malcolm

G'day Malcolm,
I have been waiting all this time for the varnish to harden enough to wet sand. What I will do is sand with 320 grit (lightly) vac and wipe down several times with denatured alcohol then apply the Behrens powdered aniline dye mixed with water onto the areas that need the print-thru hiding. After this dries - varnish the whole boat again. As for the drip lines, I will proceed as you suggested. Let you know if this works.
Cheers,
Douglas
