"moving that thing across the surface" includes rinsing a surface with water. Pressure washing is *especially* likely to scratch a surface - it seems more abrasive to me than simply spraying a surface with a waterless wash, allowing to soak, and then gently wiping with a fresh microfiber and frequently turning the towel.
But it isn't.
My soft MS paint is 100% swirl free after almost a year and 17K miles under my 3m Sun Gun. I'll bet yours isn't and if you think it is, then you're not using the right light source.
