Lumpy paint

Specifically for metallic finishes:
which is wot Im interested in

The finish,even on a brand new car is not mirror flat.
Shine a light source on the paint and the edges are rough.
What is the effect?

Is the "base coat" flat with metallic particles on the outer layer,if the paint is applied properly and its the lacquer layer that is "lumpy" to allow sufficient thickness for sanding/clay bar/mild cutting.

Or are both layers mildly lumpy?

In other words :
1. is the lacquer layer "lumpy" to provide enough thickess to remove minor blemishes without going thru to the base or is both base and lacquer lumpy?

A couple of months ago I got some surface scratches from,more than likely, some cheap ass at lidl picking up a cardboard box for their groceries.
Then using my car as a rough rest to hold their box while fiddling with getting their car doors open.

I thought I had removed all scratches, except one very heavy one, but today in bright sunlight,I could see allmost every individual scratch,at an angle

A bit "****" maybe but.

Is it better to cut a scratched area heavily first with a more abrasive polish and then polish up or use a very mild cut on the lacquer from the start, if youre sure the damage hasnt gone thru the lacquer?.

Im just wondering that if you start off too fine will you just be cutting valleys and rounding off the peaks..if that makes sense?.

Maybe its just a "experience/judgement call"

Re: Lumpy paint

My H-D motorcycle has a fine metalic paint on the tank. Years ago a neighbours young kid sat on the bike and rubbed their dirty football on the top surface of the gas tank. The gritty dust left several scratches of varying depth around 2" long and it didn't look pretty.
I bought some rubbing compound paste from the local car spares shop and after a couple of sessions the scratches had been removed and with a coat of polish the gloss was restored. I didn't relacquer the area and its been ok for years.
