Deacon 10110. Can get it at Lowe’s, Home Depot, Walmart. If your only doing one action the small tube size will be plenty. It’s easy to mix, 1 part black, 1 part white, mix until dark grey. Simple and easy to work with.
When you say "Deacon" I assume you mean "Devcon". I also use Devcon 10110 exclusively for bedding. To my knowledge, Devcon 10110 comes in one pound kits and is to be mixed
9:1 by weight .. or....
2.5 : 1 by volume .....NOT one-to-one. It has never been packaged in two-tube bubble packs as far as I know. It is also not available at Lowes or Home Depot last time I checked nor is it on the shelf at Walmart, but apparently they can order it now that they're competing with Amazon.
The OP should use caution when shopping for epoxy. Many of the small two-tube kits cure in 5 or 20 minutes. You do NOT want this stuff not only because it cures too quickly, but also because it's typically not very strong and it is likely to shrink as well.
JB weld is one option if you want small quantities, but I think it's not viscous enough. The Devcon 10110 is just right. But be careful with Devcon products too. They make several products very similar to 10110. The product numbers vary by one or two digits and some are filled with aluminum, some are very low viscosity, some cure too quickly, and so-on. In other words, be sure you're purchasing the right product; 10110 is what you want.
It's silly to screw up a bedding job while trying to save a few bucks, so I personally would not recommend a cheap two-tube bubble pack found at Walmart unless you really know what you're buying. Unfortunately the stuff most guys use, Devcon 10110 costs about sixty bucks for a one pound kit and even more if you don't shop around. It's enough to do several bedding jobs and will last at least a year after opening if stored in cool conditions in spite of what the container says. But it does have a shelf life and it is possible to purchase it on Ebay long after the expiration date; another "gotch-a" to watch out for.
I don't like Marine Tex products based on my experience with it back in my boating days, but some guys swear by it and it might be a good option since it is available in smaller quantities than a pound. Again, be careful because there are quite a few non suitable products marketed by Marine Tex, so be sure you're getting the correct stuff. I can't tell you exactly what that is, but it should be easy enough to research.
