Best Glazing Compound
Tools great, sets up fast.
Talked to the owner of Sarco on the phone and he told me their putty is rated to last 30-40 years. Apparently DAP is only good for 4, that blew my mind. An old time glazier put me onto Sarco products after giving me grief for still using DAP. It's the only stuff I use, if you can get your hands on their stained glass putty it's great stuff too.

Best Glazing Putty that exists
Best I have found. Wish it came in a metal can, no complaints beside that. I pour a layer of distilled water over the top of the putty after opening to prevent it from drying out during storage (since sometimes I go a few months between glazing projects).
