I spray a acrylic conversion varnish from Sherwin Williams. It's this one. Is
this what you mean?
I've sprayed a few gallons on pieces. It is an interesting finish. The activating agent is applied in very small ratio's, and since i typically only mix a quart or so at a time, I had to steal some teaspoon measuring from my wife's kitchen. It also requires you to thin with Xlene, 15% on first coat, 5% on subsequent coats, so it's quite the mixing operation when you're first preparing it.
I spray with a FUJI HVLP, and it goes on kind of mottled at first - I know the first time I sprayed it, I was pretty distraught and left the shop in a huff, but then I came back 10 minutes later and it had flowed out pretty nice. So I put a few more coats on. The best thing about this finish is the 30 min dry time. You can re-coat really fast. No more waiting around for hours to do a finish job.
As far as the finish - one thing that I really don't like is that you can't rub it out, so what you get from spraying is what you get. So you need to lay it down really good.
On casework, it's a nice finish - and it's now my go-to finish for casework.
Here is an example of some casework.
For surface / slabs / high grain finishes, I really think it mutes the wood grain.
here is an example of a maple burl that was OK, but not striking like I get with french polish or Behlen's rockhard.
