Hi Listers,

        OK, lets see if anyone out there can answer this esoteric question.  the undercoating on my 85 camper is in great shape.  However, there are pieces of tape covering openings in the frame.  these are starting to peal back.  I'd like to replace the tape but I would like to use the same stuff.  It lasted all this time so I'd like to use the correct tape. 

Anyone know what this tape is called and where I might find it?
