First time trying Redhead A7 anchoring epoxy. Same surprises as with others.. hands of steel required to pump the gun and only two thirds of the tube are useful. Good working time. Minimal sag. Two tubes @$18 ea. to set (5) 6" bolts. Meanwhile, the uber premium 3M 601 continues to sully my filing cabinet. THAT crap seized in the nozzle in the first few seconds and made a bloody mess of everything. Had to mix it by hand. It boasts no sag but what it is is no flow and lots of sag with about 42 seconds of working time... just a complete mess.... and a $100 gun to boot.
