Mike very well done, as always. Wetsanding is something that I've done in the past (mainly on headlights but on paint as well from time to time).

Mike, I have a question now. You say sanding in circles makes it difficult to get uniform paint/clearcoat removal. This makes sense. Now just so I'm clear, random orbitals rotate, but because they're machines, the paint and clear coat removal is more uniform and easier to control pressure as opposed to hand sanding?

great stuff,mike. when i started doing bodywork/repaints as a hobby im glad i had my sons step dad- a man with 30+ years in the trade- to guide me. cross hatch sanding(with hard block backers) is one he stressed to speed up the process and get the refinement.

I learned the X-Pattern style from Rich Evans of Car Warriors fame. He also owns Huntington Beach Body Works in Huntington Beach, California.

While this technique makes absolute sense on paper and in practice, that doesn't mean anyone can do it successfully. And my definition of the word successfully when it comes to wetsanding is 100% defect removal with out any mistakes.


Easy to talk about, much more difficult to walk the talk.

most definately. its real easy to sand through clear on body lines. also easy to not make clear flat. i did quite a bit of work on this 96 about 6 years ago. new rockers,cab corner, and lower door skins,then complete repaint. i wasnt using a long enough sanding block and had urethane wave on the bed sides,so in for 2 more coats of clear and do the process all over.

but i didnt cut through on body lines!Im the MAN
