I have also used Ron's.  When he was done you couldn't tell that there had been any damage,  Good work.  When I kept a boat at MVYC I used Ron for shrink wrapping.  He did great work at that too. 
Last year I towed a friends boat to Ron's shop in Belmont.   There was a lot of work done on the boat but it came out great.
