Somewhere I must have missed this one in the gunsmith tips and tricks...

Brownell's offers "new" Acraglas thinner/solvent in a quart can for $12. Is this something special or is it just some common solvent available in the paint store?

DeeBee, I really have no idea and (while I'm sure they have a good reason) can't imagine why they would market such a product. The thing that makes Accra-Gel so great is it's consistency. If you want to use something that flows I'd just use Accra-Glass. I keep both in the shop as well as Steel Bed. George

Thanks George-- Brownell's is marketing it because it's probably something very common and they can slap on their sticker and double the price and someone like me might very well order it! Anyway, I have two reasons to thin the stuff:

I need better flow characteristics to fill a cavity in a synthetic stock and I'm too cheap to buy Accraglas because I have lots of Accragel AND Steel Bed (I love it too) and

I remember reading somewhere you could thin the epoxy into a stock finish and weatherproof the inside (and outside if you wanted to) of a wood stock...

Epoxy thinner-- what is it? Laquer Thinner? Methanol? Acetone? Anyone see this in Gunsmith Kinks II or III perhaps? I looked in I with no luck...

DeBee, you've asked a question I've been wanting answered,too. I guess the only thing to do at this point is to try some common solvents and see if the stuff sets up as desired.

You might start with denatured alcohol--I use it to wipe up uncured epoxies and it works great. Also, Sears sells an epoxy "thinner/solvent" that I have yet to try. And I know acetone can be used to thin epoxy, but only if used in very small amounts.

Now tht you've reminded me, I may have to try a couple of things this weekend and see what happens...

Debee, the thinned epoxy you refer to is known as the Massey Finish, after a noted Alaskan bowyer who used it to great success in the wet north.

1 part two-ton epoxy to 4 or 5 parts thinner (mineral spirits, etc). Apply in coats, sanding gently between coats.

For more on this subject, from people who are experts at the application of the Massey finish, drop on it to the Leatherwall at stickbow.com. There you will find all manner of wood specialists who know what it takes to keep water out of wood.
