[Amps] Adhesives

[Fuqua, Bill L]

In the past I have found problems with many adhesives that have solvents in them.
The problem is whenever you have a gap to fill the adhesives shrink when the solvent evaporates. They fail later and if you look at the area where they 
were applied you will see voids between web like patterns . Only these thin webs connected the two surfaces.  Superglue seems to turn brittle after a while and epoxy does not
seem to work well in very thin applications.  I have gone to RTV for many applications where two ridgid pieces need to be glued and some void between them
needs to be filled. It does not shrink and gets better with time. The down side is that it does not adhear very well initally since it is fluid and needs time to
cure.  I have also used it with tube bases and plate caps on tubes. It takes high temp real well and since is does not become hard like epoxie does it 
does not stress the glass seals. GE products seem to be the best.

I would use common spray glue used to stick artwork down. Craft stores etc.
Any contact cement would work.  I used spray glue to glue sand paper to sanders to do auto body work and still do at home.
It will come off when heated so it would not work so well on anything hot.
It is very similar to what is on self stick stickers etc.
