Well, I've been printing a bunch and I have to say that I think I found the combination I like best. The Aqua Net hairspray on a smooth glass bed works great. Absolutely no warping at all, and when the spray builds up a bit a rag and a bit of alcohol cleans it right off and I can re-spray it.
That build up wasn't that bad, but I wanted to see how easy it would be to clean.
So now that I'm happy with the solution, I'm going to cut my Borosilicate sheet to size, print some clips and mount it to my current heated bed.
The next enhancement will be to use the Open Rail and make the new thinner Y Bed. Then I'll finally go ahead and clean up all the electronics and neaten everything up.
