Thx Mike,
my goal is to make my car look good 
I figured that much, what I meant was specifics, like you mention below, i.e., remove
whirls.
By the way, is that the common term everyone uses in Hong Kong to describe
"Buffer Swirl", or
"Swirls" in general? (as in what we call cobweb-effect)
Buffer swirl is typically caused by the improper use of a rotary buffer, and/or product and pad selection and shows up as
circular scratches in a zig-zag pattern following the direction the rotary buffer was moved across the surface.
Cobweb-effect is the hundreds of thousands of random scratches caused by day-in, day-out wear and tear.
I am using the DeWalt 443, which is in fact a random orbital polisher. I only have the 3M waffle polishing pads for now, but would like to get a few more pads to work with.
There is not a lot of choice in Hong Kong, but probably can get some of the meg pads here without too many difficulties.
Recently I got a bottle of DACP, but did not start using it.
By the way, my car is a 1998 black (non-clear) Lexus GS300 and has some whirls and small scratches.
Also, if I used DACP, do I need to clay?
Thanks.
The DACP should work using the 3M waffle pad, I can't say for sure because while I have tested the waffle pad, I don't use them because they don't make sense
to me.
Single-stage black paint is typically very soft, even with today's harder resin types. For this reason, you should have a high chance of success using a dual-action, (jiggle machine), polisher and the DACP. Remember to work the product until it's almost gone, and only do a section at a time, like 16" by 16". You must be thorough.
As far as claying goes. If after evaluating your surface with the palm of your clean hand after washing the car, you still feel little bumpy contaminants on the surface, then I would clay it.
Claying is fast, effective and non-evasive. The dual-action polisher is gentle, it will more than likely
glide over the contaminants versus
kick them off
Your mileage may vary.
Good luck!
