FYI, the silver tape is waterproof aluminum ducting tape. Should be able to find rolls of it at Lowe's or Home Depot in the tape area...if you've never used it, it is rigid and will wrinkle very badly (as visible in the photos) when it is wrapped down over corners or not carfully stretched as it's applied. It's also quite expensive as tape goes...usually comes in really big rolls though. Other uses for your leftovers includes putting together TK helmets...I've used it for years to tape the seams from the inside...it's the only extremely rigid tape that stays put until you want it gone, at which point it removes (somewhat tough, but not impossible) with NO sticky residue on plastic. Love this stuff.
