I have yet to perfect my CA technique. I have tried different ways, watched videos, but everytime I finish a pen, I think perfect! and see a cloud. It is usually a clouded ring at the nib or the end cap. Ihave the same resluts using thin and Med ca. Same with BLO/CA and Straight CA, same w/wet/dry sand, and w/MM. My best results have come from sand to 320, 1 coat thin, 6 coats Med CA, MM, Plast-X.....always a cloud. I use DNA after I turn, I wash my hands, and don't touch the blank. I use very little BLO when I use it, I've tried Paper towels and plastic bags. I think I'm just going to switch to acrylics........
