Conrad, great job on the build for this very interesting car. I cannot believe anyone is able to work in such small scale - my mitts barely hold 1:24 parts, and I can't even see them without a magnifier! I've been having good success with 1mm tip Molotow liquid chrome for lettering, in case you haven't tried it yet. As for the windshield, here's a little cheat I've done now and again:
I have been known to put a little strip of striping decal or window tint at the top of the windshield to cover up glue damage - or as in this case - to cover up some unsightly grooves in the windshield meant to hold the gullwing door hinges. In any event, great job, and thank you for posting!
