I am new to this forum; first I would like to say thank you for easycomposites and talkcomposites for all the tips and ideas you have shared. 

Does anyone have a problem when trying to get a smooth surface for their patterns after putting on primers and doing all the sanding? By touch, my surface finish seem fine, all smooth; however, I can still see very fine lines on the pattern even after using polishine from EC. Has anyone had the same problem? I have gone up to 1200 g sanding paper.
