Back in '65, I bought a '61 Studebaker Hawk limited edition. It was a one owner car, and I loved it! It was very similar to the car shown, but had different side trim. So YES! I would buy a couple of these for sure!
I have only used Metalizer through my airbrush. By the time I clean out my brush, I can gently rub the painted piece with à soft cloth ( an old T-shirt ). Seems to work for me.
