Ok, I read your last post.
What do you mean a V shape edge, how badly warped is the razor? How is the other side?
You might try the other side of the stone, if it is smooth it may be more aggressive if unused and you can use the two sides as a progression. I recommend lapping one side up 600 and burnish the other as fine as possible.
If you are going to lap one side, lap the bottom. When you use the 600 side, use more pressure and finish on the burnished side with lite pressure.
Ink on a dry stone will show you where you are making contact. Were you able to get a good shaving edge with you Coticule? If so a translucent will improve a coticule edge.
