Sealants for faceups?
As a few may know, I intend to paint my own faceup for my HD003 Dollfie (again, if I'm able to obtain an HD004!), but this is a slow/on-hold process because I've only recently gotten out of high-school, and don't have a job or anything XD I went to the store to look for sealant, today, and I wasn't sure of what kinds are okay to use on the type of material Dollfie Dreams are made out of. I know Mr. Super Clear is a valid brand, but I'd like to be spared from Volks' expensive shipping costs XD
In essence, what reacts (positively? or) negatively with Dollfies? A fair amount of fixatives I found had acetone in them, which...sounded like a "no" XD
Can anyone recommend what -should- or -shouldn't- be in a fixative for it to be safe to use on a doll?
(also, are normal pastels and acrylic paint okay to use for the faceup?)
