Substitute for AcraGlas

10 September 2022, 00:05

Brownells has been out of AcraGlas for a while. I like to paint on a thin coat to seal buttstock and forend where they contact the action on a single shot. I have tried a 2-part, clear epoxy sold by J-B Weld but it doesn't harden & remains flexible. Any recommendations? I have found AcraGlas Gel to be absolutely unusable. I love Marine-Tex, but it's black.
Thanks,
Roger

I use Devcon 30 min set thinned with acetone for sealing. Mix with glass floc or wood dust for bedding. Wipe it on fiberglass cloth for reinforcing (like shotgun handguards). Minwax makes a great thin epoxy to reinforce rotted wood which I hear works well as a sealer. Another great thin sealer is CA glue. Get some cheap Super Glue and soak the grain. It dries rock hard. A cat couldn't scratch it!

I use only AcraGlas Gel and it works for the application you describe, as well as usual glass bedding.

Thanks, Tom.
My problem with AcraGlas Gel is that the white, pasty component quickly goes bad in the container. It gets hard, develops lumps, and is a PITA to use. Also, it seems like Brownells changes the recipe for Gel frequently. Roger

Put the resin in the microwave for a couple of seconds

Yes, do that. True, sometimes the white part does go grainy, but a few seconds in the microwave makes it normal consistency again. I have been using it for decades and have noticed no change in the formula. Microwave oven is your friend.
Oh, the white component should Never be pasty; it should be smooth and the same consistence as the gold part.

marine-tex will take black dye - then wax it after sanding

I simply use the same West System epoxy for bedding purposes that I use for general purposes in my shop. 20 years of that and everything I've used it on is holding up fine.

I use a heat gun to soften the white resin, it works great!

I use West System and epoxy from US Composites in Florida. I recall reading a post from Spearchucker a while back where he thought the epoxy from US Composites was the same a AcraGlas.

Marine Tex comes in Gray and Black, that's all I use, it doesn't show if applied with that in mind?? I don't use it on custom stocks btw, inletting and cross bolts seem to work, and I've been told end grain in the recoil lug is stronger than glass..

maybe end grain in the recoil is strong as stated, but what about the 100% contact wood (or glas bedding) to metal factor?

For that application, go to Walmart and buy Gorilla Glue two part epoxy.

Roger,
GunSavr gunstock finish in satin is clear & dries quite hard. That'll seal it right up. CB

Due to low conversion rates and shipping $USD / $AUD I make my own brew. I find any epoxy will do the job. I use little graduated medicine cups for mixing.
to 7.5 Ml of mixed epoxy I add 1 heaped teaspoon of Carbosil and make up a stirrer from a bent piece of wire, it takes quite a bit to mix it in properly, I then tint as required and if needed add stainless steel powder. Sets up like the Rock of Gibralta. Caution is needed with the carbosil, it is similar to powdered silica and can cause asbestos like illness read Cancer. It is so light it will float in any breeze, once mixed it is harmless
I believe the West people sell the carbosil
