Thanks Mark,
I kind of wondered the same thing,that if I had to replace them,how would I be able to easily get them out.
Originally,I planned on using epoxy to bed them in with,but thought it might be a b--tch to get them out if I had to change them.
I know 5200 is also permanent,so I've been giving some thought to Sika-Flex 291 lot.I use it quite a bit,Its a polyurethane like 5200,but a little less permanent.
I'll look into the life caulk,thanks for the info.

One advantage I have,is that the boat will only see freshwater (the Great Lakes)
