Terry,
A heat gun will work just fine to get the bulk of the undercoating off. Start on a low heat setting and move up gradually until you find the temperature that works the best. If you use a putty knife to scrape the udercoating off, be careful, it can marks on the underbody fiber glass. I would use a hard plastic bondo paddle if possible. It will not damage the underbody fiber glass surface.
Then you can use bug and tar remover which I think is made by Turtle Wax. You could also use kerosene or 3M weather stripping adhesive remover. Get yourself some rubber gloves that will not be affected by the chemicals, I think nitrile rubber will not break down. I'd use medium to fine 3M scotch brite pads to remove the remaining undercoating. A tooth brush works well to get into the corners and small nooks & crannies.
Hope this helps.
Best Regards,
