[Tigers] bulb dye

[Rollright at aol.com]

Hello,
 
Most of my career I've worked for consumer electronics companies. Back in  
the 1970's, working for a company in Cambridge. MA called Advent, we used a  
substance labeled "Bulb Dye". It canpackaged in small bottles inside a  
transparent blister mounted to a cardboard backng. We used it as a sealer for  
tweeters; an outside coat on the working diaphragm. Red for Large Advents 
and  Green for early Smaller Advents. (some really useless trivia)
 
Someone just wrote in about vinyl dye and it jarred my memory. I've been  
wanting to ask anyone if they've seen this stuff on sale anywhere. 
 
Reason?  The red generator light gets faded and this would be just the  
ticket to restore it. Yes, I know you can turn them around and I've got a good  
one now, but I'd like to play around and see if this works on the ones that 
are  too far gone other-wise.
