I build plastic and resin model cars as a hobby also. I should say I buy lately not so much build. I had a can of paint that is actually a FCA paint (Jeep/Chrysler) that I have no idea why had bought it but thought it looked like a good shade of silver. I didn't prime the wheels because I plan on building and just displaying it. I will maybe clear them with a Tamiya clear. They look great and I will post some pictures here as I finish up the rest of the car. I love this Lego btw.
