Ohh... the numbers are SUPPOSED to be on the outside, I see what you mean now.. I thought you meant on the paper they were floating in the space between pieces. The tabs are meant to be glued on the inside. Can you post a picture of what the problem is so we can avoid further miscommunication? If the tabs are physically on the outer surface of the piece, it may or may not be a problem. It may not be if the bondo ends up covering everything. It may be a problem if you sand down too far and hit the tabs and cause them to fray out.
