acra glass is great stuff. it just stinks to high he**. It isn't flawless. Measuring by volume is a pain.
I Loctite 120 is really good stuff also. I'm surprised so many guys sprung for the dispensing gun. I'll get it added to my assortment. It's drawback is the dispensing gun expense - which is one time I understand.
the 2 part epoxy I have is from Bob Smith Industries. It is good stuff and I use it myself.
It is NOT the best, most durable expoxy out there. I think Loctite, overall, makes the best adhesives out there. I have been reading up a bit and see there are some adhesives that outperform 120hp and I can't understand how that is possible. I will keep researching.
