youll be able to tell by the absence in orange peel. the smoother it is the better shooter he is and/or more color sanding done.

What is the difference between wet sanding and color sanding? I have a pretty good idea of wet sanding is and how to do it, but I have heard that color sanding will give you a better/smoother finish. Can someone give me a general breakdown on how to do this?

Same exact thing. Wet sanding is a term used a lot of sanding of the clearcoat on a 2 stage paint job(base/clear) and some use the term color sanding when talking about sanding a single stage paint job, but basically they are interchangable terms. Both use water and very fine grit sandpaper(1500 plus) and both have to be buffed out when finished. Goal is to remove orangepeel.

most of the time when people refer to color sanding they are refering to sanding the base color. Of course this is done with the wet method. Now when people say wetsanding they can be talking about any sanding that is done with sandpaper and water, but usually they are talking about sanding the clear coat on a car. The most dramatic results on a cars finish will come from wetsanding the clear coat to get rid of all orange peel and then polishing it out. Generally you will not need to sand the base coat color before clear unless your painter doesnt know how to lay the paint on. wetsanding the clear is not used in most auto body shops when they are cranking out the cars but when someone is paying and looking for show quality it is a must.

Thank you both for the answers. Now second question is do you think that the Menzerna IP polish is rough enough to buff out the finish after wet sanding or is something more abrasive needed?

Not sure of the brand, but if it is just a straight polish, it won't take out the sand scratches. A good clear-coat safe rubbing compound (I use either 3M Perfect-It II, III, or Meguiar's Diamond Cut), then a good machine glaze, and then polish will get you the best results.

It depends on the sandpaper grit and the machine/pad combination using the Menzerna.

Best to start with a compound to get the scratches out unless you want to spend a lot of time with the polish.

I was thinking of using the Menzerna IP with a yellow pad and then the Menzerna compound right below the IP (can't remember name) with an orange pad. Sound like a good combo, or no? Oh, with the PC listed in the sticky at the top of the forum.

ZaneO

With a PC or rotary?

The random orbital one that can be found at Lowe's.

It's pretty tough to remove sanding marks with the PC (not sure if that's the machine you're talking about). It can be done, but be prepared to spend *lots* of time and effort.

Yep, that's the one. Thanks for the info. I might take a stab at it eventually.
