They are all more or less the same AB, I haven’t used this one but it seems ok and $20 seems more then fair
Here is some info I found and the product of theirs I would carry, I carry one very similar

Description:
J-B Stik Weld is a hand kneadable, steel-reinforced epoxy putty adhesive/sealant that will plug holes and make permanent repairs on wet and dry surfaces. It will even cure completely submerged in water or GASOLINE! Simply knead thoroughly, with your fingers, a portion necessary for the repair and apply. J-B Stik will fully cure 20-30 minutes; and can be drilled, sanded, filed, tapped, machined, and painted. J-B Stik requires no tools or “prep time”, and makes no mess.
How does it work?
Simply knead thoroughly, with your fingers, a portion necessary for the repair and apply.
Hope all that helps
