Sorry for being the "bumpmaster" once again (especially on a two year old thread!!) but im getting into the propionate game now and this last question is pertinent to my situation.... As most of you know, i live in Georgia where it is ungodly humid... My prop is dissolved in straight acetone but can i add anything ( MEK, thinner, etc) to slow down the flashoff of the acetone and hopefully prevent blushing? Im only using prop as a sealer so its entirely possible im getting worked up over nothing but im turning to you guys for a little advice !!
