I am trying to switch over to water base finishes and have tried Crystalac Brite Tone on a couple of guitars. When I level sand, I got what looks like witness lines in the finish on both guitars. The picture below shows what I get on one of them. It was hard to photograph and much more visible than the picture indicates. Everything I have read indicates witness lines are not a problem with this finish. So why am I getting this?!? What am I doing wrong? For background, it was sprayed in ideal conditions around 70-80 degrees and low humidity using a 4 stage HVLP turbine. I scuffed with a gray scotchbrite between coats. Once I understand what went wrong, the question is what to do about it. I can buff it out and see if it is visible but I imagine that will just make it pop more. I already put on more coats once. The lines went away with the additional coats but came right back when sanding. I'm debating just putting some 2K urethane over it since I know that won't have the issue but I don't know if that will hide the lines like the additional coats did before or just magnify them under the different clear. I appreciate any advice or insights people have.
