I can see you used lots of different modeling techniques in your build, and hand painted graphics too. Keep up the good work, keep learning, keep trying new things, and keep trying to improve your skills. That is all there is to it. Have fun
I forgot you mentioned decals still needed to be applied. I must say that I know nothing about decals over wax, or wax over decals. My decals are usually under the clear coat. Someone will be able to steer you right. Good luck!
I've got a couple of rather fine brushes that I use. One is a 10/0 and the other is a 3/0. The #'s don't tell me much as to they are both so small. They come even smaller. Either of these seem to work well for me. The brand is Atlas Brush Co. Tamiya makes nice, small, pointy brushes also. Good luck!
Engine is looking good. You have done a great job with the proper routing of the spark plug wires....running under the exhaust manifolds where they belong instead of over the top of the valve covers and then down. I think alot of builders run them over the top just to make sure everybody can see that they wired the engine.
One of these days there is going to be a post in "Under Glass" with a scale build of this thang. Will you be the one to post it? Can a post be made anonymously? Is anybody at their bench right now feverishly working on it to be the first?
