I'm using Nelson Hobby's Flat PolyU clearcoat and it's not "flat enough" for me. I've heard of guys using talc/baby powder as a flattening agent in clearcoats before... Anyone have any experience doing this with Nelson's clear or any other waterbased/PolyU clear?

I'll probably go ahead and test this, but would like to hear of any experiences you may have had and/or how much powder to mix into the clear when shooting it through my HVLP detail gun.

Thanks,

Tom
