I want to have some graphics made to put on my tank and I'd like to know how i should have them made and how i can apply them. I was thinking of just having them cut out of vinyl, put them on the base coat and clear over top of them. Is this ok? Will any vinyl work? How big should they be, and do I have to wait long after I spray the base coat before I put them on? (I should mention that I have these decals in the proper format to be cut out on a regular sign cutter)
