I wasn't convinced that using the Van's "baggie method" to inject ProSeal between the turtle deck skin and the rear window would lead to anything but a mess so I bought a couple of 100 ml syringes to use. Worked Ok. Acceptable, not great. The main problem I had is I used electrical tape to protect the turtle deck aluminum skin and when you curl it according to the instructions to allow access to the screws, it actually curls over and onto the window at the two rear curves. I have one thin spot -- the curve on the pilot side -- but I'm going to leave it as is. It's fine. I kind which I'd done a better job with the filet process. I also have some adhesive and ProSeal remnant on the skin I need to get off. Can't use chemicals; bad for acrylics. I may just sand with 400+ grit. We'll see.
