Hi guys and girls. Going back to some of the basics as I believe I may have tried to advance too soon. Having a problem with my lines most of the time. I seem to get a dot at the start and stop points. I am moving the brush with air on and then back for paint, when at the end of line, with brush still moving and air on I release paint and get the dot. Wicked Paints, reduced to 6 drops reducer to 3 drops paint. Krome and 18 PSI. Thanks in advance.
