Bedding a chassis, looking for marine tex. Local ACE hardware has it but what type is recommended? Thank you. Reason I ask, I tried acra glass but it was paper thin behind the recoil lug and of course chipped away badly.
 
I'm really not sure if I didn't screw up the entire job. It didn't get a good bond with the aluminum. That and a lot overran the dam around the tang. Marine Tex seems cheaper and easier to find.
 
Regarding the Marine Tex, get the gray putty, the rapid set doesn't have enough working time to be suitable for bedding in my opinion. You should also rough up the surface of the aluminum and thoroughly degrease it to help promote adhesion with the epoxy.

BTW, what chassis are you bedding?

I am not an expert by any means but I have bedded a lot of rifles with Marine Tex grey and it has always turned out excellent and holds up. I even use the stuff to repair pitting inside of diesel engines (mostly in the coolant jackets on sealing surfaces, like liner band seals). I have gone back and rebuilt some of those engines 700,000 up to 1,000,000 miles later and it is still holding strong. The trick is to prep the surface properly and get your mix right then let it cure fully. It is tough stuff if done correctly.

Excellent, that is what I ordered. I'm bedding an MPA ultra lite for the updated R700p barreled action(5r barrel ect.) . The gun was on par with my old Sako A7 accuracy wise while it was in an H&S precision stock. Its had accuracy issues since landing in the chassis.
 
10-4, did you try playing with the torque values at all or just torque them to 65 in/lbs?

I'm asking because I have an AX AICS chassis and if I torque the action screws on my Remington 700 AAC-SD to 65 in/lbs I'll have accuracy issues, however if I torque them to 55-57 in/lbs. The AX is from the first generation that has a traditional v-block type bedding interface so my guess is that torquing to 65 in/lbs instilled too much stress on the action. Right around 55 in/lbs seemed to be the sweet spot where I could get sub-MOA performance without bedding.

I can give that a shot as well, I have tomorrow off so I'll try 55 psi, its currently 65/66psi.
 
I have done a lot with marine tex.
All on boats.

It is tough and will outlast you.

One thing about using the kits,
Do not weight it out or anything like that.

Mix all contents thoroughly and use them. No screwing around.

My brother has a boat i repaired 30 years + ago and it still holds.

For a gun no use for quick set. Use the standard stuff.
