How do you make registration letters/numbers stick to a PVC inflatable? We put them on yesterday, pulled the dinghy out of the garage to bake in the sun today, thinking that would help the adhesive set, but this afternoon the numbers were falling off. How do I make them stick? The dinghy is a BRIG. the surface is not smooth, more like a pebbly vinyl automotive dash board.
