Wow. I just came here to ask a very similar question. I am stocking up on kits (kinda) and am looking to load up on RLM colors. The only local hobby store has the whole Model Master line and I think I would prefer enamels since that's what I used to use. Kinda wondering what the "must have" colors would be.
Looks like you an I are in the same adventure of a return to the hobby. Good luck with the new airbrush!
