Been some time since I've been on here so not up on the "latest & greatest". I am finally finishing up my bottle of Duragloss 521 that I used for bird bombs and everything else a QD might be used for. Are people still using this as their goto QD, and if not what have you moved onto? I tried ONR as a QD but it didn't handle the tougher stuff as well. Thank you! :xyxthumbs:
