i've been using gunzilla for years and love it. i've used it during 2 high round count carbine courses with zero problems but i also used a good amount on the weapon. it's great for cleanig and as far as i can tell good for lubrication. i've heard great things about slip 2000 ewl and wanted some opinions by people who have used both for lube, people who have taken high round count courses i would like to hear your opinions . i'm really only looking at these two products, thanks in advance for your input .
