I'll add my .02 on Akzo. Its superb and stupid easy to use. I shoot it with a primer pistol w/film canisters - forget the HF gun or any gun for that matter. The pistol is the best for this primer. I tweaked mine to shoot at 10psi (yes ten) though I like 20 better - allows me a little faster travel speed with good coverage. I use a 9 gal cheater tank, regulator, 2 mechanical driers and a last chance drier onthe gun. I can shoot 2or 3 of canisters before refilling the cheater tank - and its highly mobile. Akzo flows and coverage area is superb for the amount you mix up. Dries on the part in as little at 10 mins even at low temps, though I give it 30 no matter what if I have to flip parts to prime the opposite side.
Shot full side skins and small parts the size of your finger with the PP. I draw the components up in 1floz syringes and mix it in a dixie cup (someone else here on VAF mentioned this and its a top notch idea). Can and have mixed as little as 10ml at a time right in the film canister and its no problem. Shot it as low as 40F and as long as 24hr old - put a saran wrap lid on the cup with a rubber band. At 24hr age shooting was ok, though a bit slower in drying - not much really. It kept for 2 days in the garage at 55F, but by the 48hr it had solidified. Up to that point, I keep it in the cup and use a q-tip to touch up drill holes, edges or what not. I clean up with acetone as long as it hasn't dried ie for syringes, cups, gun etc. If its dried forget it. You have to scrape it off.
Speaking of which, I did some tests early on - primed out of the box AL - no scrub, no acetone wipe, finger prints all over it. It stuck pretty good, but with some good mechanical action it came off. So my prep is 7447 Scotch using Crystal Simple Green (not the same as regular SG - I use CSG for oxygen service cleaning - can't get better than that), tap water rinse, and an acetone wipe. Sticks permanent - I need a grinder to get it off this way.
I do use a full face mask and HomeDepot zip up paint tyvek suit, but I shoot it outdoors always so the suit keeps me warm a bit too. I'd say its really no worse than any rattle can fumes, but since I bought the stuff out of an abundance of safety, I use it.
YMMV; but mine in this area is outstanding. Originally, I wasn't going to prime all my inside skins - leave 'em bear and hit the inside with CorrosionX every few years. But the Akzo is so easy and bullet proof, I changed my mind quick.
