Sealing windows while refitting

Thanks for all the info. What type of silicone did you use?

 

I have had a look but can not find which type/make it was as it is not in my Ebay purchase list as i got it from the local PVCU/window fitters come suppliers, they do loads of type of sealant and this is used for window fitters a lot that work with aluminium.  It is not a silicone but a sealant adhesive. 

As long as it is water proof and UV resistant it will be fine. Even Sikalfex 291i will be fine just add the thin bead along the outer edge and as Alan says in the 2nd post says smooth it in once fitted.

This is just second measure along with the neoprene tape.

Not sure if this is similar to anything already suggested but I've just replaced all the windows on my nb and sealed them with butyl glazing tape, easy to use and looks very like what was originally used by the boat builder. 

Re silicon, for reasons best known to them they also ran a bead of silicon around the window edge, this has subsequent caused rusting after 6 years under the silicon possibly due to trapped acetic acid during the cure.

'Arboseal' butyl tape.

Used it on Innisfree's brass portholes, superb stuff, it's a bit like bluetack, sticks well but stays flexible and can be peeled off at a later date. 

 

ETA: Keep some handy to use as a gasket to bed in all sorts of things, can be used like putty.
