Micromarring/ DA Haze is a common and expected result of heavy compounding/cutting. Luckily, it is easily removed with a proper polishing process.

In the following picture, you can see a severely damaged panel with massive amounts of defects that requires heavy cutting to level.

M101 on a MF Cutting Pad via the Rupes LHR21ES easily leveled these defects, but resulted in a considerable amount of marring (to be expected on this softer, jet black paint)

A medium compound & less aggressive pad was then used to quickly (2 passes) restore some clarity by removing the heavy marring, however this still left some marring that needed to be refined.

Finally, a couple quick passes with M205 on a white polishing pad produced a clear finish without marring.

This can usually be accomplished in just two steps (cut then polish), however given the substantial marring we encountered after our cutting process, it proved easier to do two quicker steps rather than one longer polishing step to refine the surface.

Hope that helps

Lots of good info already added by Evan and Zach.


Couple of things....

Lots of options for compounds and polishes that don't micro-mar the paint or at least do it less than other products.

Pads
Fiber pads are more prone to leave micro-marring than foam pads as each fiber that makes up a fiber pad has the ability to leave it's own scratch in the paint. (micro-marring is at its core scratches in the paint).

Removed paint and spent product residue
As you're removing paint it builds up on the panel and the face of your pad. You always wipe it off the panel without even thinking twice about it but what about removing these two residues off the face of the pad?

IF you don't remove them you'll be grinding them back into the paint and these two residues can cause micro-marring. This is why I always say, work clean.


Someone mentioned residue control the other day ago... here's one article I wrote on this back in 2010


Why it's important to clean your pads often... (http://www.autogeekonline.net/forum/tricks-tips-techniques/28755-why-s-important-clean-your-pads-often.html)



Here's another one I wrote back in 2014

Tip: Clean your pads often! (http://www.autogeekonline.net/forum/ask-expert-featuring-mike-phillips/81585-tip-clean-your-pads-often.html)



Both explain the problems and the solutions.


Remember... clearcoat paints are scratch-sensitive. This means that even though they are harder than traditional single stage solvent-evaporate paints like lacquers and enamels they still scratch easily.

Thus working clean by keeping your pad clean is important in order to avoid or reduce micro-marring or even deep swirls when using a rotary buffer.

Here's an article on this topic....
