AFAIK, di pwede yan. Dangerous kasi. There's a big possibility that you'll damage your paint if used improperly. Masyadong mabilis ang ikot ng angle grinder. You'll end up burning your paint. Kung alaga naman ang paint mo, use an orbital instead. Yung angle grinder kasi is comparable sa rotary buffer. If used incorrectly, SUNOG ang paint mo. Rotary buffers are used for restoration purposes only. FOr maintenance purposes, use an orbital buffer.
