I have never painted 5 rockets at the same time before, and I hope never to do it again. I used one can of primer yesterday between these four rockets and my Blue Bird Zero. I have been real busy so my models have been on the back burner. I was hoping to have these done in the next couple of days, but in-laws have altered that plan. I will probably finish by next week some time. So far these builds have been real easy and fun. I applied 3 coats of balsa sealer to the balsa, primer and one top coat. Now I have to mask 2 of the rockets and paint the other colors. My Testors Inca Gold came in today so I will give it a try.
