[Alberg30] Re: Bedding Shroud Tangs

[Carl Clarkstone]

I expect many will dissagree, but after using sikaflex and 5200 to seal my 
shroud tangs( both of which started leaking within a year) I used plain old 
clear RTV, I used a fair amount to build up a nicely filleted bead around 
the tang and this has been absolutely leak free for 7 yrs, I also had 
approximatly the same experience with the windows!
It appears to me that sikaflex and 5200 just weren't elastic enough.
