Long after I was a child and I wanted to do a few Mopar muscle cars, I got a friend to mix the body colour in acrylic enamel... and painted the other parts in
water-based acrylics, then gloss or dullcoated them.
The acrylics work very well, dry a LOT faster (for recoats and fine detail) and look a little less "model paint" unrealistic in the end.
Loved going back and doing models as an adult... had all the patience to do the things I didn't as a kid, like painting "Fram" on the oil filter, adding scuffs to the tires for realism, painting the dashboard gauges, etc.
Still want to someday get a model, and build it as a beater, use the soldering iron and styrofoam cutter to add rust holes, etc...
