Hand sanding before clear coat: My go-to move for a perfect finish

Most body shops push power sanders for speed on final prep. I get why, but I've seen too many jobs with micro-scratches from orbital sanders. Early in my career, I worked on a Mercedes sedan that needed a perfect gloss. My old boss taught me to use a sanding block by hand. It felt slow at first, but the finish was mirror smooth. Now, on every repair, I spend extra time with hand sanding. It lets me feel the surface and catch any lows or highs. Some guys say I'm too picky, but my customers never come back with complaints.

All that hand sanding sounds like perfectionism run wild. Do you really think it's worth the extra hours?

When you say perfectionism run wild, I get it, but sometimes that hand sanding is the only way to get a finish that feels right. If you're making something you'll use for years, those extra hours pay off by making it nicer to touch and last longer. But it's easy to go overboard on parts that don't matter, like the inside of a drawer no one sees. Knowing when to stop is key, or you'll drive yourself crazy lmao.

Hand sanding for hours sounds like a special kind of madness... but @nancyn69 gets it. Sometimes you just need that smooth finish, even if it drives you nuts. Just don't start sanding the air around the project.

Honestly, the quiet time with hand sanding is the best part. It's like therapy where you actually get something done at the end. You can't zone out with a power tool the same way, you're just fighting the vibration. My brain sorts out all kinds of stuff while my hands are busy making something smooth.
