I have a few questions on the AKZO primer.
It looks like the smallest quantity is 2 gallons. Correct? Is that enough to prime an entire RV?
Does this stuff keep well? Would it loose anything after 5 years of storage?
Has anyone ever sprayed this stuff with an airbrush for small jobs?
Thanks

I've used a cheap external mix Badger airbrush for small jobs. One oz. mixed seems to go a long way and it's real easy to use and clean up with a little acetone.
Careful with the Harbor Freight external mix airbrushes - the plastic in them will melt with the AKZO.

I'm using AZKO to prime the -12 I'm building. I've used almost a full gallon (2 gallons if you count the activator) doing the Empennage/Tailcone and Wings. I don't think 1 gallon will do an entire RV-7.
When I did my -7A, I used a number of different primers. At some point Walt gave me "expired" AZKO that he got from a user that had to adhere to official shelf life limits. It wasn't 5 years old but it was a few years old by the time I got it and it was better then anything I has used to that point in the build.
I just ordered another gallon last night. Thanks for the Graco tip, definitely the best price around.
I'm using a Sharpe gun with PPS cups. I'm still developing my technique.

The two gallon kit is 1 gallon of primer and 1 gallon of activator. It is mixed in a 50/50 ratio. From what I have seen on the forum, the official shelf life is 2 years, but others have mentioned using some that has been older than that. YMMV.
I have the PPS adapter and the shipment of AKZO and Prekote on their way, so I will be attempting this for the first time soon. I think the practice kit will be my first victim, er, I mean target, er, object to test on.

Yes. I use a small Badger (cheap) airbrush all the time for small parts and in conjunction with the larger gun to get in tight areas. Works great, easy clean-up. http://www.badgerairbrush.com/BADGER_250.asp
Also, to prevent wa$te, I use two syringes, one for each primer component, to draw out small quantities for touch-up, etc. I mixed up 2cc (1+1) the other night to prime the spar nutplate countersinks with a small brush. (little insulin type syringes) The primer won't cure in the syringes if you use a separate one for each can.

So I have decided to go with the AKZO primer. But at that price, I sure don't want to waste any. If I use the PPS system, mix up primer but don't use it all, can it be stored for future use?

Takes 30 min after mixing for first use, then 8 hour pot life; less if you have a small amount.
The cost at $150 delivered for a gallon of paint is actually really cheap. 128 ounces mixed compared to $6 plus tax for a can of spray paint that has 12 oz only 6 of which end up on your parts. So thats 20 cans of spray paint or about $120; and the AKZO is tough as nails and so much more satisfying.
On an $100K airplane, a couple hundred bucks in paint is nothing; build on!

Once you get a good technique, measure the primer and calculate the coverage. Then going forward mix only the amount needed.

Also, I see that the PPS comes in different cup sizes. Which cup size is appropriate for priming parts?
