I was thinking about going for a gray bubble. I do have a clear one, unfitted, that came with the salvaged Skybolt I bought. Today I decided to clean it up by getting all the protectivecling-film off of it so I could inspect for any scratches before I decide to sell it. This film has been on the bubble so many years, that most of it seems to have adhered to the bubble. I cannot get it off. I have tried breaking it down with MEK, acetone, water and soap, wd-40, . A finger nail will actually take off a little bit, but forthe time it took me, it would take me 10 weekends to get it stripped! Any ideas?
