I bought some cheap waterborne (rust oleum ultimate WB poly) to pre-coat some baltic birch ply I'm using for drawers. Once the drawers are assembled I will need to do some final coats on the edges and joints. I'd like to spray and I don't know if the RustOleum will spray in my HVLP gun. But, I do know that GF HP poly sprays well in my gun.

Should i I expect any compatabiltiy problems with the GF over the other brand? If so, then I'll just bite the bullet and apply with a brush. It's just a lot quicker and easier to spray one they are assembled, especially on the top edges of the drawers.

maybe I just need to do a test. If so, what would be signs that the finishes aren't compatible?
