I really want a Catalina to paint and play with so I purchased one from Shapeways not realizing how gritty they are. I understand there is a process one can use to smooth it out but I have no patience for that and am not convinced it will not end up with detail removed (largely due to skill level). I was looking at the AIM model and was wondering if their stuff is smooth plastic or gritty like the 3D printed models. Also, if anyone has purchased the Catalina it would be great to hear about the look and quality of the model. It seems like people on this site are happy with AIM in general so I assume, generally speaking, the quality is high.
