I have a '97 Willie and I am thinking of removing the Gluvit and re-applying it. I once heard of some "stuff" that would basically dissove it like paint remover. If anyone knows, the info would be much appreciated. You can by Gluvit at marine supply/boating stores. West Marine has it. You can buy it by the quart or gallon. It is expensive and you have to mix it with catalyst to use it. It has a fair use time and as long as you keep the components uncontaminated and above freezing you would probably save money by buying a larger amount. That way you can touch it up as the season goes along. As you know you have to get the thickness right. A tip that may help anyone that uses Gluvit is to mix graphite powder in for a little extra slickness. Just be careful not to use so much you mess up the cure. I also block up the boat just off the trailer so I can do the whole bottom at one time.
