1/144 is our scale. We are in Planes, Vehicles and accessories that the big Modelkit-companys dont offer. Here a few tips for our first time buyer :
All materials will have some surface roughness, so you need to sand that down. The materials are strong enough to take rough sanding, but details and thin parts can be brittle depending on the material chosen. Please use a dusk mask during sanding.
You can use any paint on it. If you get the Frosted Detail or Frosted Ultra Detail materials you probably want a primer just because the material is translucent once it is sanded smooth. Putties and 2-part epoxies will also stick to them if you want to fix problems or add detail.
