Can we talk about paint booth air flow and what I missed for 5 years
I've been spraying paint in my booth for about 5 years now, and I always had trouble with dust and dirt getting into my clear coat. I blamed cheap primer, bad prep, you name it. Then last month my old timer neighbor Bob came by to borrow my DA sander and watched me spray a fender. He asked me if I ever checked my booth's intake filters. I told him sure, I change them every 3 months. He laughed and pointed out I had them in backwards. I felt like a total fool. The arrow on the filter frame was pointing the wrong way, so air was pulling through the dirty side first. I fixed it that same day and my next job came out clean as glass. Has anyone else had a simple filter trick that made a big difference in their paint jobs?
