Re: [PSUBS-MAILIST] sikaflex suggestion

A second thought on this is that I've always worried about Sika not setting up. It looks to me like it would just keep squeezing out during every dive until the plexiglas lands on the steel.

That is what I have heard about RTV. So I am assuming then you would use
Sikaflex. It sounds right but there about 400 different versions. Hard on a poor old
boy like me.

I haven't looked into it. Mine were bedded in RTV, which sealed effectively, but were not what I'd call great fun to get out again for paint, etc. Sikaflex doesn't cure the same way, and never takes a set. RTV is, of course, the acronym for room temperature vulcanizing, and they ain't kidding. It bonds and sets up something fierce. The other problem with it is that RTV can't be repaired. It won't bond chemically to itself once the original application kicks. Meaning that if you have a leaker, you get to try out the car jack again to break the port loose (and hope that the RTV is the ONLY thing that breaks). In either case, you have to start scraping and go back to square one. What a pain. Trust me, there will never be another submarine in my garage with goop sealed ports. Never.

I have been looking at sikaflex for my viewports and did not realize the number
of types.
 
Any suggestions on which one to use?
