Sure Jim, enjoy the sanding! I should also mention that International paints makes a very good epoxy sanding putty. You can get it at West Marine stores I think. that will eliminate many of the problems of mixing variations.
BTW, try using spray primer applied with a squeegee for filling pinholes. It beats the Hell out of spraying on $300 worth of primer and sanding off $295 worth of primer as a means of filling the pinholes. Te problem is that spraying isn't particularly good at filling the holes. Squeegeeing takes a little more time but you mix about half of a dixie cup to do a whole wing and the sanding is nothing. It will take a couple of times to get them all though but your agregate time is less and you save a pile of sanding. You might also want to consider doing an indicator coat of gloss before spraying the final coat. For that, I mean if you plan on having a flawless finish, spray on a coat yourself to see the pinholes or flaws that are left before you pay a pro a lot of money to do it for you. Many flaws can't be seen on a dull primer finish so even if you don't do as perfect job, it will save a lot of money.

Thanks Daniel,
I ordered the small container from ACS to try it out. I see lots of other
opinions favor SuperFil and I ordered a quart of it too. So I guess I?ll
fill and sand some to see which is better for me. It?s hot in Houston and
that will be another variable in my 100 degree plus garage soon to be.

West system is pretty good but it isn't remarkably better than Jeffco,
Saf-T-poxy or any of the other basic resin system's like that. It fairs
well but as pointed out before, it will always have variability in the mix
since variaons between batches cant be helped. Also, acetone can be added
to thin it and make it runnier but it does weaken the mix significantly.
And I always use a mix of Cab-O-Sil and balloons since all of one or the
other isn't good. Balloons only
makes for a very "dough like" viscosity
when it becomes thixotropic. And all cab-O makes it hard as a rock to sand
and is like Vaseline and doesn't spread well. 75% balloons to 25% cab-o
works well though.
