Panel seal (rubber tape)

Having stripped out floor panels,seat box etc from my 90 to do the clutch. Upon replacing seat box etc there was a run of sealing tape between the panels, as some fell off some was missing and some had missed can anyone tell me what sort of tape it is and where I might get some. Thought it was self amalgamating tape but that is non adhesive any ideas gratefully received ....

id replace it with a more modern type stuff

same stuff used to hold articulate trailer roof skins on

Power Double-Sided Tape, Neoprene

That looks good stuff, have just been searching on Internet and found something similar 'storm guard ' tape from screw fix only thing that concerns me is that they won't be waterproof. Not that my 26 yr old landy is that water tight anymore ....
