As far as I know "Polycrylic" is a brand name of a specific acrylic varnish made by Minwax. So there'll only be alcohol-based stuff if they decide to make it.
Don't let that keep you from searching for what you want, though. Just try to find the right generic name, and search on that.
I've done four planes now using Polycrylic as a base, and I've only had warping problems on one of them. They're all profiles, two of them hollow. None of the problems were with the fuselage.
The problem that I did have was with the most recent, a Fancherized Twister, where I got really enthusiastic about not getting any gaps in the center sheeting on the wing. Basically made it over sized and crammed it on while gluing it up, and compounded my error by not gluing it firmly to the ribs. As soon as I hit it with the Polycrylic, it swelled up. But, given what I saw when I tore it up and re-glued it, I'm not sure that it wouldn't have warped up on the first really humid day, even with a dope finish. Given my three successes so far, I think my one failure can be traced back mostly to the assembly.
I avoid dope first because I don't want have to manage the whole issue of toxic, flammable vapors coming off of my building project. I'm using Polycrylic second because I can waltz into Home Depot and get my painting materials rather than having to mail order them and spend a lot. It would seem that a paint product that uses any alcohol at all gets you right back to "flammable" and (even with ethanol, to some extent) "toxic", so I'm not sure you're gaining on that issue. Add to that the fact that unless your desired paint is available easily you're back to mail-ordering stuff. All in all, I'm not sure you'll gain much advantage.
And, if I could get dope at Home Depot for the same price as Polycrylic, I think I'd be figuring out how to arrange for better ventilation in my shop, and using that.
But I'm interested in hearing of your experiences!
