The clear covering on my Superfly frame has some inperfections. 1. There is an area on the TT where the coating has some spider cracks. If not adressed, it looks like it will start to peel. 2. There is also a small visible bubble in the coating on the opposite side of the TT. I can live with the bubble but would like to avoid the coating from peeling. Is there something I could use to seal the coating?
