I would highly suggest toning down on the pastes a bit. Overuse of pastes will create a wire edge, and paste will not be able to fix the resulting damage. Sometimes too much of a good thing isn't very good, especially for razors.
Typically it should take no more than a dozen laps, depending on the type of paste. Start at 5 laps and test. As Lynn always says, less is more. Definitely sage advice when it comes to pastes and sprays.
