Why don't you just use electricians rubber tape. It's the same stuff and any electrical wholesaler should have it. I'm not sure, is your tape semi gloss or flat black? The electricians tape is flat black. Just some info rather than paying to much and shipping costs. If you want I have some 396, L-79, L-88, Z-16, 572, rubber tape that costs less than that for sale. Sorry, I've been looking at ebay adds too much.
I'm not sure the rubber stuff is the same. If it's the same stuff I looked at work, non adhesive, but rather soft and dull, kind of sticky in a way. I'd think it would attract dirt.
The actual harness tape is glossy smooth and slick. Really just good quality electrical tape without the adhesive I'd think.
Cheers.

Well, the guys at work all accuse me of liking big boats so I guess the Strato would qualify. Might as well ship it now and I can use it during the flood!
