Especially is your are using an HVLP, the heated air flow accelerates the evaporation. However, if a retarder is used, flow-out is improved and the surface tension has a chance to smooth out thus reducing the orange peel effect. I procure my shellac flakes from homestead.com. The last time I ordered, I acquired the retarder but have not had the opportunity to spray shellac. The one time I did spray shellac years ago on a portion of a plate; I got a real grainy finish. So now I have the retarder for my next touchup job.
