Are you applying the graphics on a horizontal surface? I have found that no mater what application fluid we use, (we used to use rapid tac but after being publicly "confronted" by the owner of the product, on several different occasions, we have started making our own application fluid in house) after we have thoroughly squeegeed the the graphic down, we stand the sign up vertically while it dries. That does the trick for us. Gravity will slowly work any extra application fluid out the bottom.
We figured this out after realizing that vinyl applied wet on a vertical surface never had the same issues that we were having when we applied vinyl wet onto a sign that we was resting horizontally on saw horses. Once we stood those signs up to dry, we noticed a big difference, Even when we were still using rapidtac.
