Hasn't been discussed here for 10 years or so but:
- To overlap (stick separate gasket mylar down both sides overlapped by 5mm in the middle) or not (ie just one strip cut down the middle)?
- To cut a "V" at the aft end (self-emptying is the theory) or don't bother ('cause it doesn't actually work)?
- Glue (ie CT1) or Double-sided tape (eg 3M VHB)?
