Help with Grinding wheel for angle grinder....what kind?
View attachment 1715020914 Very much agree with Pascamp, post 10. Flap wheels have a place in my shop, but usually not removing paint from a body panel. A flap wheel is made up small pieces of sandpaper glued to a hub, for it to operate correctly the paper is being slowly chewed up and new sand grit and paper takes its place. If the wheel is plugged with paint, primer or bondo, the wheel will not cut and you have a heat problem. This depends on the paint, there are different kinds of paints used I can easily check this by taking a small piece of sandpaper and sanding the car with it, if “balls” on the paper, it will ball up on the flap wheel. Sometimes I do use a sanding disc for large flat areas gently operating the grinder, taking the time not to press into the work area. I don't like having grit marks into the sheet-metal, that's if you don't mind buying the expensive fill and cover primers. The sanding disc can ball up also, usually I take a wire brush (clean one for this purpose) and or an eraser to clean the disc regularly. I like chemical strippers but not all strippers will work well on all paints, you have to experiment. For the chemical to work well you have to glob the stuff on, it does not work if it feels dried, gloves please. You must have the part flat, it will not work properly on door or fender hanging on the car. My own personal feeling, keep this stuff out of body seams and corners, and do not use this around areas that have foam fillers and adhesives, such as under the hood to support frame. Or you may have an dis-attached hood and you may have paint crinkles at the seams where you use the stripper. I by far use the abrasive wheel and the small abrasive quick loc discs. Here again quality counts for me its 5 to 1, HF discs or one 3M disc your choice you decide. I would like to express safety here please! Face mask, safety glasses, gloves, making sure you have the correct wheel for your equipment rpm. They can fly apart whether if they are cheap or not.
