Newbie looking for knowledge *1st set of pictures*

OP stated this:

"I have started sealing the edges with buytl tape (which has been a pain, it's so sticky on my fingers but not too sticky when it comes to sticking to seams) "
===========================

I'm at least a little confused by this statement. This sounds like you may be using butyl tape for an application that it is not intended.

Can you clarify, and maybe with a picture of where you are using it ?
