3D modelling question

[Bozothenutter]

A question for the more experienced 3D modellers.

When it's time to print, is it a good idea to add texture?

I'm making a 1/35 painted cast iron part. (Mark IV final drive)

In that size you'll probably be better off working with a paint that gives a slightly rough finish. I don't know the real parts, but from my work experience with casted parts they are not extraordinary rough - the surface is as rough as sand on a 1:1 part. Because that's what's usually used to make the form.
