anybody use Marine-Tex for bedding a "plastic" rifle stock. had a old kit probably 10+ years old. the only issue is that the compound is very stiff. any thoughts on a thinner??

Devcon works well too. I see Ken has weighed in in this. I can’t add more

Devcon aluminum putty epoxy, 10610 ... " F " ... is the Devcon i use ... it is great, not overly sensitive to mix ratios, and i have never had a failure with it. after putting in the desired area, it will slowly level, does not quite run. at room temps, you have a safe 15 or 20 work time minutes before it starts getting tacky. sets in 45 to 90 minutes, ...

if bedding a gun with factory stock bolts, after about 2 hours, i loosen and retighten all the screws to insure the release agent ( kiwi neutral shoe wax ) is working. after 4 or 6 hours i separate ( more insurance ! ) the metal from stock gently . then remount the stock and let cure for 3 days before shooting.

Devcon is very reliable but comes in a costly can ( $60-90 ) which is enough for 5 to 10 bedding jobs. it also is a kinda ugly dull aluminum stuff, but Brownells sells pigment.

hope this helps, ken

... don't toss that Acraglas ... it is good epoxy. and the shelf life is years and years. cool and dark place.

if it is the unfilled type, it is great for fixing split stocks and as a " killer glue " for many things around the shop and house. also a non-rusting patch for your automobile.

even great for mounting non-intrusive scope mounts on a gun you aren't taking into the elk mountains but just want to see how it shoots with a scope. weaver or picatinny one-piece base is ideal ... lots of surface area. to get it off, heat with a hair dryer and give a sharp whack with a brass hammer. dismount scope first, of course.

just some trivia, ken

A similar weld with metal-containing epoxy helps to hold the bridge on my "unbreakable" titanium eyeglasses. It looks awful, but it keeps them together.

gently warming epoxy will thin it ... but CAUTION ... warming will also make it set faster ...that can be fine or a disaster ...

marine tex is great for bedding.

i take it your question is about it sticking to a " plastic " stock.

i always .. even in wood ... take a 1/8 inch drill bit and make several little " anchor holes " at different angles in the stock for whatever goo bedding to settle in ... kinda like the roots of a tooth ... when you dollop the bedding in that area i work it into the holes with a toothpick. the bedding goo will settle smoothly.

... and .. once in the field doing fishery samples i broke my plastic glasses frame right between the eyes ... sanded the surfaces, put a wad of good epoxy around the break and held them together for a half hour until the stuff set up. let cure a couple hours... a risky butt weld but it was a permanent fix tho it looked silly.

might mention you don't need a lot of epoxy for a good bedding job, a 1/8 layer is enough. you can get by with a $15 tube of JB Weld from a local hardware. use the standard, not the 5 minute stuff.

just some trivia ... ken

If your compound is stiff try micro waiving it for 30 seconds at a time until it softens. Marine Tex is pretty thin when new and fresh. I’ve brought Acraglas and other epoxies back that way based on Brownells recommendation. Marine Tex works fine as bedding compound and for setting pillars when you are pillar bedding. It is extremely durable stuff, but harder to manage the Acraglass Gel. It adheres to plastic and fiber glass very well if the surface is roughened and degreased with something like acetone.

I hate to say this, but I went went to the Super Shoot in 1997, Brunos had a tent set up, and I bought a quart of Marine Tex then. I still have it and it still works. Now, I have used it for this many years, and it has developed some thick things in the can. I no longer use it for bedding an action, since any hard spots would be an issue, but for bulk filling, it works as it did all these years ago. Do NOT sniff the catalist vapors, it will blow our sinus'' clean!

It is a great bedding compound and I use it all the time.

It works, like any product similar to bedding compound will work. If I remember correctly, it was listed as an alternate before the standardized epoxy bedding compound came into usage.

Experiment with a little on wax paper. If it cures slowly, resists mixing or in any way looks bad, throw it away.

I once spent an late morning and entire afternoon assisting getting a Remington 788 action out of the stock because the release agent was too old. We split the stock and then spent the rest of the afternoon relieving the wood inside along the cracks and gluing the stock back together. With stripping, sanding, and a redo of the finish to oil, the cracks almost looked like ribbons in the walnut (early 788 .30-30) from five feet away.
