Hi, I received my shipment of Shapeways models and used acrylic type paint, it failed miserably lucky I was able to remove them. It won't stick to the surface, it can be easily be removed. What am I doing wrong? Can someone please please tell me the step how to paint a FUD model starting from taking the object out of the box. It's my first time and my budget is very short. Cleaning- What is the best way? Primer- what kind is the best for tiny models? Paint- I would like to have semi-gloss type. Not too flat or too shiny, what is the best brand? Please help! I don't want to screw up even more on my models. The model size is about the size of a pencil, but 5cm long.
