Time for an update. Today (technically yesterday) I did a second cateract on a rectangular tube, Letting the tubes sit in the sun extra long seems to eliminate the need to electrically heat the wire.

Again I was able to roll most of the PVA off, but was getting tired of the limited effectiveness of windex at removing the residue.
With that in mind I sought out someting better while at the hardware store for the double stick, and clear sillicone caulk that I've read is a good way to reinstall the safety glass.
And found this product which is much much better at getting the PVA residue off (though it almost seems to fog the safety glass in the process, but maybe the glass was that way from the beginning?).

I used that whole bottle and cleaned everything spotless except the round CRT(which I started to clean before running out).
I couldent get 1/4" wide 1/8" thick foam double stick tape, but if I cut this lengthwise and stack two or three high I belive it just may work. Is this a bad idea?
Will any caulk work to seal the safety glass after remounting, or is a speciffic type needed? This is what I plan to use. Is it the right stuff?
