If it were me doing this paint scheme, I would follow Steven's advice. The difference being for me is that I would paint the red, mask it then paint the silver. The problems I have had with some silvers is that the masking tape would pull some of the pigment off. It would not pull an entire layer of paint like some of us are accustomed to, but would pull off perhaps a little bit of the paint here and there leaving a silver painted area, but it was very splotchy.
As far as the model kits, Monogram issued a kit of a Chapparal that has been released and re-released over the years. There are several on ebay. I built this one a number of years ago. It has a low parts count, but today it remains one of my favorite models.
I have been using Future for about 20 years and it is my "go to" for a gloss coat. I put it on using a medium flow setting on the airbrush and then quickly sweep the airbrush over the model at a distance of about 6 inches. Future is thin and will run, which is why you don't want the airbrush staying in one place for very long. When I have all of the panels covered, I let it sit for about 15 - 20 minutes and apply another coat. I will usually apply 4 - 5 coats. The thing that I like about using Future is that I can "read" the finish and adjust how I am applying it. If it is drying and the finish looks like real small pebbles, I am spraying too lightly or too far away. If it is drying in larger blobs, I am applying it too heavily. The good thing is that Future is self leveling to a degree and you can usually smooth out these problems with the additional coats.
