I’ve been thinking alot on the whole window water intrusion/sealing/rot issue (forced to by current work). I’ve been using pieces of remnant rolls of certainteed ice and water shield (“weatherwatch”), granular faced, as lapped flashing around my windows. Are all ice and water shields the same, or should I spend extra for the Vycor? Anybody seen really old ice and water shield?
Also, none of these can be left exposed indefinitely, right?

I think you'd be better off using peel'n'seal instead. I know it may be hard to imagine, but it sticks 10 times better, and comes in 4 and 6" rolls already.
I wouldn't be using heavy stuff with surface that you are only because of the thickness that might make siding/trim lay at an angle to the rest of the house. Vycor is thinner than regular bituthene to let it lay tighter over the flange with less buildout. Add the convenience of having precut widths like Kieth said and it's worth while.
But it is a good way to use up short ends of the other.
Excellence is its own reward!
Thatguy,
I have never used Vycor but my crew uses a probably similar product called "MFM Window Wrap." It's foil-faced with a sticky tar-like coating on the underside, and comes in large, tape-like rolls. Just don't stick it on bare sheathing or wood---it won't stick! As for flashing membranes, we use GAF Stormshield, which is probably also similar to the stuff you use but it has a smooth face instead of granule-coated--we use it for lining valleys under the felt whenever we have woven shingle valleys. GAF recommends not to leave the product exposed to the weather for more than 60 days, BTW.
