: that rubber.

George,

not at all...today's two piece golf balls are quite hard with no loose rubber windings inside. In fact they drill quite easily 8-)

To add to post below, reference your velcro adhesive situation. In my last career I owned a sign business and have removed more adhesive than I want to think about, heat is good, but I can understand your concern, Therefore I would suggest that you wait til a nice warm day, and apply an adhesive remover. They are available at most automotive stores under several brand names. They are pretty potent, so you might try just a little in an inconspic loc to see if the chosen product attacks your boat. The trick is to dampen a cloth with the remover and keep working on a small area at a time, the stuff evaporates extremely fast, and so you are continuously back to square one if you let it dry. In other words keep the adhesive damp and softening, and keep removing what you can as you go. Another product I have had good luck with is "goof-off" sold in most paint departments. If the adhesive is particularly reluctant, you might try dampening with the cloth, and then scrubbing with one of those nylon wool pads. Be sure to work in a well ventilated area.

Good luck, best regards
Ron
