The ship will be made out of painted metal, which is going to be worn in specific areas. I do not want the ship to look super shiny, so I want to have the specularity map reflect this feature. I can do this by only using dark colours on the specularity map so that it isn't too shiny, also I will use grey colours because at the scale the ship is at, you probably wouldn't be able to see much colour shining off of the ship. Again I have chosen a boat to stand in for the fictional creation of a space ship, so I have posted a picture below to show how shiny I want it to be, as well as showing a similar colour scheme.
Thinking of some ideas for what kind of bumps would be on a space ship, I had an idea that it might have some kind of dimples over the hull of the ship to help it's aerodynamics in atmospheres, just like a golf ball. I have shown a close up of a golf balls dimples below so that I can try and explain my idea. The normal map should have circles on that get darker in the centre so that it looks like a rounded dimple, rather than the holes just coming out of nowhere.
These dimples look a little bit close together for how I want my ship to look, I will space them farther apart on the normal map.
