I bought a second hand pair of tubular wheels and am in the process of replacing the tyres. I haven't glued tubs before and have read some of the old threads with advice on how to do it.
My problem is that the old tubs seem to have been glued on with some kind of prehistoric duct tape which is a real pain to get off the rims. It's pale blue and looks like the tape is cloth based cos there are threads running through it.
I soaked the whole lot in acetone and then peeled it off, but that took about 40 minutes and almost detached one of my fingernails. Any secret tips on getting this tape off the rim, since I still have one more wheel to do?
