Are there any special provisions for using JB Weld "steel" for bedding a rifle in a wood stock?

I assume that it would work pretty well, and any car or shoe wax would make a good release agent.

You have the idea.....cary on

JB Weld works fine. Use a fresh package. It can be pretty thick at room temp and if you need it to flow better, use a 75-100 watt bulb with reflector to heat the mixture or tubes for a few minutes to make it flow better. It has a good working time so this won't cause it to set too quickly. I use a couple coats of wax for release agent. To avoid voids, paint a thin layer of epoxy on the action in areas of concern before you drop it into the stock.

Just get some Devcon Steel Epoxy.

What's the difference between
Devcon Steel and JB Weld steel?
Both are available in 'two tube' 2oz versions.
Devcon also has a one pound version that needs to be weigh 1:9.

I can't tell any difference in the devcon and j-b except j-b is more readily available locally and not as expensive as devcon.

I use Marine Tex from Brownells mostly..I have not use JB weld to bed with but I have taken it out of stocks and its extremely hard and a lot of work to remove..Heating with a hair dryer makes most bedding easy to remove, not so with JB Weld, it doesn't seem to soften much.

BTW to avoid voids , hit the wet glass after you put it in the wood with a hair dryer for a few minutes, gives a nice clean bedding job.
