I just stumbled across this thread. I like what you have done with the glass. I have the same kit on the bench, and the bubble-like glass is the most disappointing part of the kit. I figured it was unworkable, and set about making a new windscreen out of .010" clear plastic. But the kit body is designed to use the deeply relieved glass, and therefore my new windscreen was too deep-set into the body. It wasn't a good look. It never occurred to me to try to sand the back of the kit glass. It's a much better solution. Cheers.
