I took a class in PDR back before Covid. The bad news? We spent all but one week of the semester doing plastic welding. The good news? I learned plastic welding.
But I learned enough PDR basics to get started. My goal is to remove all the ripples in my 968 fenders. The metal is so thing that if you look at it sideways, it leaves a mark. But I need a lot of practice before I jump into that.
