I have one last idea on the Stained Glass if you do not mind...
I LOVE that idea, so I hate the thought of giving up on it. Maybe later, after this bike show, you could play with a JB weld type of gray epoxy to attach the colored baubles into the plexi/acrilyc/lexan windshield.
That would still give a gray colored, kind of solder look but not require the heat that cracks the wind screen...
Maybe mask up all of the baubels and plexi to keep the JB lines fairly straight, pull the tape before it sets fully hard...play with some test samples?
Not trying to tell you what to do of course, just throwing out a thought. The SG would REALLY finish of that look and give it that POP.
Great job Beez!
