Re: [bolger] Re: finishing a hull and hiding blimishes?
I have used a Sandvik long handle scaraper with success to remoce runs
and othe large imperfections.

I think it also depends on how your going to finish the boat. I use 60 grit only but paint with a roller so getting a super smooth finish is a waste of time. Using a random orbital sander does wonders for not leaving scratches even with 60 grit unless you put a lot of pressure down on the sander. Using several coats of primer and two or three coats of top coat paint will fill all the minor scratches left by the sander. Plus the roller marks are leave a slight dimpled finish that hides the minor sander scratches completely.
If your going to spray paint, then all bets are off and the best thing is to finish with at least 100 grit and use some sort of filler.

If you are going to put a third epoxy coat do it now but don't sand it
with 80 grit. Wash it well and sand with 100 or finer just to take off
the gloss. The 123 will fill the finer scratches and recoating with
123 is a hell of a lot cheaper than epoxy. If you are over exuberant
about your sanding you will find than you have areas with almost no
epoxy. Sand most of the first coat of primer off then recoat and sand
for finish only.

That 80 grit will leave some scratches. Your options are to try to sand them out with finer grades of paper or to fill them. Filling can be done with micro balloons in epoxy (mixed to a fairly thin consistancy--thinner than peanut butter--and applied in as thin a layer as possible--you are only trying to fill in the scratches--you'll have to sand this smooth too) or some sort of surfacing putty (I usually go through a tube of the red stuff sold at auto paint stores for each boat I build). You can spend a lot of time striving for a "gold plate" finish. I have; but have yet to achieve perfection! At some point, I give in, say good enough, and go sailing.

I'm planning on three coats of epoxy regardless for sealant followed
by two coats of primer (the bullseye 123 stuff), then 2 coats of
some good old white exterior latex. I don't beleive(?) the paint
