I am about to get into the same kind of project on my boat this week. What did you find that works the best for removing the adhesive and in my case foam from the ceiling? I am considering using Zolatone to cover the unfinished glass. It's kind of a splatter paint, comes in a bunch of colors and textures and hides imperfections like you wouldn't believe. It has to be sprayed and I'm not looking forward to taping and masking the interior three times. Once for primer, again for a base coat and the last for the color/texture coat.
Give this a click.
