Anthony, I think you are crazy for priming with black. The only color you will be effectively be able to paint over it, is well, black. All the possible german camouflage options all use light and medium colors, but no dark ones. Perhaps you are going to give it a custom paint job? Also is that gloss black? I recommend using a light flat gray for priming. It makes detail easy to see and it can easily be painted over. I hardly ever prime to be honest. I spot prime over putty spots.
Dj I take it you are building the 1/35 Tamiya one? It is an outdated kit with numerous errors, but it makes a good model to look at, well not the interior at least. The AFV Club and Dragon ones are far better. The AFV club one has the most detail and correct overhang, but for more than the Dragon ones with all the extra goodies.
I'll repost this:
I am nearly done with assembly of my M-26 Pershing. All the body and details have been assembled. The wheels and tracks are off along with the side panels.
