I have used Modge Podge. It covers well and gives me the finish I want. BUT after six months or so it apparently dries out and frosts with millions of little fractures deep with the smooth finish. You can see this a little bit in in this picture: http://s36.photobucket.com/albums/e9/mo ... D7Base.jpg
The sparklie bits were just the beginning. Now they have connected the dots.

Said sealer shouldn't eat my brain with harmful fumes. And, since I don't used an airbrush, I am hoping for something that I can apply with a brush or sponge.
I suppose Future might work but it would take maybe twenty or so applications to get the finish I hope for.
Any suggestions?
