[Paddlewise] stripping urethane from S&G kayak

Hi!
   I would appreciate any advice on stripping urethane from a peeling stitch 
and glue wooden kayak. The fiberglass has a few dings that need filled, but 
the finish is the main concern, as I will be trying to sell it immediately.
     One person suggested I remove all the loose finish, sand the edges and 
the old finish to give the new coat good adhesion, and put on a new coat. The 
reasoning is that the urethane is only there for UV protection, so if there is 
a layer of Urethane (or polyurethane, not sure what the difference is) the 
product is doing it's job. The proper thing to do would be to inform the buyer of 
this, and warn them that if spots appear (fail), more work will need to be 
done.
    I would prefer to remove all the finish but time is at a premium. The car 
wash certainly helped remove the finish where edges were loose, but that's 
only about a quarter of the boat.
 
     I can buy commercial stripper but am not sure it works on urethane, or I 
could try a brass wire wheel in a drill, or I have a heat gun (probably good 
for making holes in the boat, I don't like the thought).  Or, would acetone or 
denatured alcohol do any good? TSP? 
     All help appreciated! The faster the method, the better!
