1. Being the cheap skate that I am I currently use a 3M window insulating kit for 'mastic' and 'bagging film' No kidding! It was hanging out in a corner of the shop and I thought, "let's just give it a try." I suppose I will eventually have to order some professional grade 'stuff' but until this is used up, or doesn't work any more, I'll stay the course.
That aluminum channel was a last ditch effort to seal what I thought was the culprit seal letting in the air. It turned out to be somewhere else.
B. Yes I have a pair of 42 STs up in my boat supply room. I sent you a private message.

I started taking a series of pics last night on the whole bagging process as I do it. I won't say that I'm doing it right, but when I first started looking into this process there seemed to be alot of DIY techniques. Some kind of sketchy and tight on info. So I thought we'd buy a manual from the Gougeon Brothers. It turned out to be a general info guide and a bunch of sales lit. Go figure. Then I tried contacting a few people actually doing it. Jack pot. Turns out it's not rocket science! We'll see what happens...
