The ALK-200 that Carter sells is sprayable right out of the can. But it can also use ALK-201 hardener and can be thinned up to 10% if needed with Xylene. I found some 1/2 pint cans of hardener (which is enough for a gallon of paint at 15:1 ratio) and used that. I also found that thinning just a touch gave better flow-out.

I found a Tech Sheet for the AUE-300 urethane and it looked way more involved than the ALK-200. It required hardener (rather than optional with the ALK-200) at a higher mix ratio.

Here's the Tech Sheet for ALK-200. I was on PPG's website and it's listed under their Versolon line, but was unable to download a current Tech sheet for it (or any others for that matter.)

The Accuspray gun I bought is for the older PPS system, and supplies are getting a bit more scarce. If I were to buy a new one I would go with the newer system, just for the availability of supplies. The gun with 4 different size nozzles, a cup and I think 4 lids and liners goes for about $300 on Amazon now. You can get various size cups and liners (I used a number of the "mini" (6 oz) size cups for smaller jobs.) Cleanup involves filling the cup adapter on the nozzle with solvent and spraying it thru a couple of times, using just a few ounces of solvent. The liner and integral filter in the lid get tossed.
