What I meant is that I think a lot of people use Modge Podge matte or gloss to seal the hair. It looks like it coats nicely from my experience. When I wet hair it gives me no problems at all. It dries fairly fast, Usually in about a day the hair can be coated a second time.
I also bought something called Modge Podge Dimensional Magic, that stuff is great and dries in like 2 -3 hours but it is better for tears and repairing tears in thick vinyl. I am going to test it on lips, nose holds, nails, and tears because of the fast dry time because I am using resin right now and this Dimensional Magic is so nice and dries fast.
