I've used both the TI paste and crox with my razors. I was able to go about a year on a razor before it got to the point where the paste and crox couldn't quite bring it back. I used the TI. On an extra leather strop that I had, doing about 10-15 passes, then followed up with crox on balsa for 15 or so laps, then webbed strop followed by regular leather stropping. It worked pretty well for me and I was satisfied with what it could do.
Is this a common thing to do?
