http://www.penturners.org/forum/ Search or go to finish forums. Also much cheaper to buy from one of their vendors, ExoticBlanks. They use it for finish as well a gluing. I find the thin has very little strength but does penetrate well. Should seal well. Medium has more strength and takes longer to cure which is good working time.
I like glass better because it seems more flexible than CA. I thin it and use heat to get extra penetration. No reason you can not use glass over thin if you want. But I seen both used and they both seem to work well if surface is very clean and oil free.
