From Most Aggressive to Least Aggressive ---->
M105, Ultimate Compound, SX 2.0, SwirlX, M83, M205/M80 (same cut rating, but two different types of abrasives), SX

I have UC, SX 2.0, and SwirlX as M83 wouldn't remove all traces of swirls, etc. out of my black paint. Just need the time and place to detail now!

 

Thanks again for the product info. I have been on Meguriars site reading quite a bit so I may have eventually found this or asked. You save me a question or a bit less searching and reading.

I used this version of ScratchX and I hate the powder.

Wax Shop products are pretty much powderless so I guess im spoiled.
I have been using wax shop products for some time by hand with fair results. With a DA the possibilities are limitless it seems.

SafeCut seems to be better at scratches and swirls than ScratchX with no powder residue.

 

I've never had a problem with powder unless I got to a dry buff which is bad as well. Is the SX still clear and oily looking when you go to wipe it off? If not, you may be over buffing it. You don't want anything to dry except the waxes.

 

Oh man....
Over buffing.
I thought I was "working the product thoroughly into the surface."
Good grief....an answer to a question I never knew to ask.

 

Hehe, all of the magical tricks of detailing. Learn from experience....and speak from it every now and then, lol.
