Thanks everyone for your reply and comments. I'll upload the engine room picture and some other pictures later after I upload them.
The Oregon license plate came with the kit.
The Testors one-coat lacquer is a great paint that airbrushes like a dream. I have used it before with ease and good results as shown in this Camaro concept car snap kit:
The Western Select clear coat (RS6200) mixes with the hardener (RS9002) in a 4:1 ratio, just like many other urethane 2-part clear coat. It is just a lot cheaper than the name brand. The hardener comes in two temperature range: 55F-75F and 75F-95F for different drying environment. Here is a picture of what the can looks like.
