I just played around with the Spray Max two part rattle can stuff (I know you said no to these but why?) it seems like a good product and at about $25 a can delivered, it’s about as cheap as mixing your own given the price of paint these days, unless you mixing really small batches. I do not know how to multi quote sorry. As,far as the guns I use they are HVLP Sharpee. But my screen was cracked so typed wrong sorry. The Spray Max is great but is once and done as the primers and paints are catalyzed so can not save what's not used for later. If I needed thst much I woukd use my gun. I have PPG DP40 epoxy and Evercoat 2K Slicksand High Build in my cabinets. I saw the SEM etch cans but did not know thet had high build thanks. I build or work in its if small things and was just looking for the ease of spray bomb it for later vs turning the compressor on, mixing primer, getting hoses , hooking up an extra water separater. Then mixing primer clean gun and pick everything up for just a small part like I have been doing.
Thanks for all the replys

one of the best spray bomb primers i ever used was, believe it or not, the red oxide "dollar store" brand. great coverage, stuck well, sprayed well, very durable even when not top coated, and was only 99 cents for a "large" size [bigger than the normal size] can. a couple of us bought out the whole stock when it was delivered each tuesday [wednesday maybe, i forget] late afternoon. however, like most good things in life, it was discontinued.[sometime in the mid 80's, i think] as we had quite the stock built up, we used that stuff for years after we couldn't get it any more. another good thing about that stuff, was it sprayed as it should even when the stuff was old, unlike some cans today that just spit when they are old, no matter how much you shake 'em to mix.

I read that you can re-pressurize an aerosol can with an air hose after pulling the nozzle off the can. I've never tried it but maybe someone here has. i've done this, sometimes with mixed results. you need a good, rubber tipped blow gun [that seals good around the can port], preferably modified by enlarging the internal orifice[s]. this gives extra air volume, which helps tremendously. regulate the air pressure to 100lbs, place can on floor or other comfortable position so it doesn't move, place blow gun over can port so it seals, then apply pressure until you hear it equalize, just like filling a tire. if you have been successful, can will now spray. if not, look closely at can port for dried paint or other crud, examine rubber gun tip to be sure it seals the can port completely, then try again. it does take some "learnin' " to do this, [at least it did for me. ] so don't get discouraged.

For a basic "air dry", I do like the SEM primer. The guys that mentioned the "moisture cure 1-component" urethane in a spray can & mix/spray 2-component epoxy (I haven't seen that) are definitely correct about MUCH better durability vs. an air dry primer. fyi- urethanes will take sunlight, but epoxy won't + epoxy is much better vs. gasoline/alcohol chemical resistance vs. a urethane

Yes, you can do this with a tire stem, and it works for a few days. Eventually the outside air that is now inside the can will cause the paint to dry up and harden. Search You Tube for a video.
