I called my buddy, Jeff Rogers at Airplane Plastics Co in Ohio. He said that
the plastic that usually comes on canopies has a water based glue. He suggested
putting a little water under the edge, let it sit a few minutes and see if it
loosened any. The chemicals that you can use on acrylic canopies is: isopropyl
alcohol, mineral spirits, white gas, kerosene, naptha
Jeff and I began to talk about another method to remove the old plastic. High
pressure washer! we laughed about him cleaning his dirty four wheelers and
washing off the warning labels and me cleaning my sailboat with pressure
washers. We think that might be the fastest and easiest way to get it off. Take
it to the car wash and give it a try. Start with an area that might get cut off
or covered up with fiberglass when you get ready to install it to make sure
this method is OK.
