I went to the shop for the annual rear suspension service. I have the Fox Float R, which is already few years old. I am not sure how old as I bought it 2nd hand.
A day later I got a phone call from the mechanic that the cylinder has a dent on it and that this might cause air to leak through the new seals. As I was not around to see it and as I have no experience with this, I told him to go ahead and replace the cylinder. I payed around $120 for the full treatment + replacing the cylinder.

But when I got there and saw the cylinder and the "dent" I was surprised - it is so small and so shallow it looks like a thin piece of paint flaked away. My camera is not that good that it can show how shallow it is but I estimate it is only as deep as 1-2 hairs (!).

Do you think the mechanic was correct in replacing the cylinder or was it just to make some more money on my expense

I added a photo so you can see what I mean. But if you want to read more information, I have it here.
