I'm hoping someone can help me out with this. When I turn a platter around 12" I apply WOP on a bit of cheesecloth while turning the lathe by hand or setting it to around 50 RPM. If I use gloss WOP I get a beautiful finish no problem. When I use satin WOP I always seem to get circular application lines that just don't seem to even out. The can of WOP is only about 6 weeks old so I don't think it's aged beyond use. Should I thin it with mineral spirits to try to make it flow better? I don't really seem to have a problem with a smaller bowl, only on a larger platter. Any ideas?
