Expert Q & A …. Sanding vs. Hand vs. Buffer
Yes, it does take a lot of time to buff/polish rims and parts! Even if you have a buffer/polishers and proper wheels /rouge bars it still takes time and patience to produce a desired finish. Many DIYers experience adverse effects when polishing. For instance, micro scratches/burning the metals can happen from improper speeds and applied pressure. Temperature is also important. Which is why people hire professionals to do this. And it’s probably a lot more economical than you think.
We aren’t saying you must hire professionals. In fact, there are many videos out there with detailed information on the steps and proper products to use, so you’ll end up with the desired results. Likewise, there is just as much disinformation, so be careful and be sure to fact check before using any product on your vehicles or parts! Be sure to practice on scrap materials before touching your rims or vehicles. Technique is just as important as products, temperature and tools. Ask anyone who learned the hard way, damaged metals can be costly to restore.
Long Answer short- Research & PRACTICE. There are no shortcuts.
