I called a company that makes diamond spray and he said .05 for a straight razor is ridiculous, because that is only used for tiny computer chips. He suggested I use 1 micron and .25 micron to refine my edge. I ordered a paddle strop from SRD a few months back and just now realized that they included a bottle of .50 micron spray, so I have three grades of the stuff.
So after I finish honing, I do 100 laps each on the 1 micron, the .50 micron, and the .25 micron. This is not for refining the edge, but to see if the hone job will last longer.
In terms of maintenance, before and after each shave I do 10 laps on the .25 in addition to my regular stropping routine. Occasionally (maybe every 1 or 2 weeks) I add 1-2 sprays of the .25 to the felt to refresh the strop. DrMatt357 is pushing a fabric strop with .10 micron spray for maintenance purposes that costs $50. He claims that will extend the life of the hone job for "years." His "perfect" hone jobs are $35. I am improvising a little from his concept.
Actually I believe what Lynn Abrams says, that .50 micron is more than satisfactory but I had the .25 so I'm using it before and after each shave to see how long the edge will last.
I have a 400x USB microscope and the best honed razors I have used (purchased from Classifieds here) don't usually have the mirror finish, so I'm just playing around with diamond spray to see if I can make their hone jobs last longer. I get somewhat of a mirror finish but don't get all the scratches out like DrMatt357.
