If you wanta model to turn out PERFECT you airbrush EVERY last part, including the smallest one. I am in the process of building a Ferrari Testorosa 521 TR and once I airbrush the interior pieces I can finnaly start pieceing it together. Its not a cheap approach, but if you want a modle to be perfect, you airbrush every piece, wait for it to dry and TAKE YOUR SWEET time building the thing. I havent built a model in 1 year my last one was the Revell Drag car, let me tell you i was impressed with my own results, Ive buitl about 30 models before, and you dont start seeing the perfection until after about 10 mdels, anyhow, I quit building and now found this Fererrai for cheap at a agarage sale and it being my fav car I bought it. Its turning out great so far. Ill get some pics up when Im done. Good luck on your project and remeber take your time..
