As an (now-ex) motor body builder, I know what you are saying.
I used to build hearses & the majority are still painted black, it throws up a challenge to the person doing the work.
If you're getting a custom made frame, tell them that you want to paint the frame black, ask them if they think that finishing the welds would be better (remember you are dealing with craftsmen, they'll want stuff to be reflective of their skills), they may charge you a little bit extra, but if they know up front you may want the welds finished, they'll weld it a little deeper & leave a little bit on top so they can finish it with a grinder & flapper discs, we used to virtually get a flat surface when we were finished, a little bit of filler, some spray putty & it'll look like it's just a molded frame.
Or if you want the welds to show, then let them know so that they can be just a little more careful & leave a very pretty weld.
Most craftsmen can do it either way, but they need to know up front, don't be too afraid to let them know what your plans are, give them the chance to show the world their skills.
Oh & take them back some photos of the finished result so they can show others just what they are capable of.
