Thread: Which tape?

Hi all,
i have been honing my razors for about 4 years now. I use a Coticule mostly, and have had great results. If I need to restore a bevel I use a 1200k Bear and then finish on the Coti.
Now, that is my hollow ground razor process. I have just started to get brave and try to restore some old near wedge razors. The question is, what tape should I be using? As I used 2 layers of insulation tape last night, and although I got a good result, the tape had worn in places on the spine. This has given me an uneven bevel. Am I using the wrong kind of tape?
When applying the tape I made sure it was totally symmetrical both sides. I started with my 1200 Bear and finished on my Coticule. Probably inadequate process for a wedge.
