Hmmmmm, just to throw a little flammable liquid on the fire.
Went to Amazon, got an order of Tamiya tape 18mm x 18 meters for $5.00 with shipping (if my math is correct, certainly not guaranteed due to my last measurement of cubic yards of dirt, this comes out to 8 cents a foot.
Found some 3M® - Vinyl Fine Line Tape from Amazon 3/4" by 36 yards at $15.67 with shipping (again if I did it right about 14.5 cents a foot.) Found it at a local auto parts store for about the same.
So I think I'll try the Tamiya.
IIRC correctly, I think I read Tim Van Milligan's daughter did a presentation on the different tapes at a recent NARAM, and Tamiya came out on top.
Of course, now this will just remove another excuse I have for my crummy paint jobs........
