Should be able to use if nothing else, Cant think of the name of it?
My daughter use's a lot of it. Its a water based paint.
You might have to mix your own to make orange, But it would be safe for glass but might not withstand a rain shower?
Or plain old white shoe polish. I'll look around here and see if i can find some of hers and maybe get a name or brand off of it.
On that' would you give the ok for anyone else to use the VOLNATION.com in that same respect?
