Hi Hulin
Try Loctite 406 by Prism.I have never tried it on latex or silicone but it might be worth a try.I have used it on most other plastics,nylons,rubber,neoprene & elastics with great success.Your diving helmet sounds pretty excitng,would you be using an existing but modified fibre glass...
Any old hands know the modern equivelent of a Philbrick T-52 op amp,or better still point me towards agood reference site on the net.I have tried the Bur-Brown ref.but no go.
many thanks.
