D4: Meguiar's Microfiber Cutting Pads

1. Microfiber, by design and make-up, grabs things and holds onto them.  You'll want to have some kind of air source to blow out the pads often when using with a polish.
2. I generally only get these out of the cabinet when I am going to get more aggressive.  So I would typically use when I have scratches that won't come out with foam and a milder polish.  Use with Jescar Correction Compound, Meguiar's M105/M100/M101, Scholl's S3 Gold, etc.
3. I think it is important to prime these by spreading polish onto each fiber prior to use.

These come in 3 sizes and only come in 2 Packs.  I think you will want at least 6 of each size.  I have 12 of each in my cabinet.  All slightly oversized on their respective backing plate sizes.  This offers a degree of safety when approaching edges and curves.

• 3" is 3.25"
• 5" is 5.5"
• 6" is 6.25"

I clean them in the sink using Optimum APC after every use.  If you take care of them, they generally last a long time.  Don't wash with anything that leaves a residue behind that could affect the paint next time you polish.  Dawn leaves something behind on the pads, so it is recommended you don't use that.  I also rarely get them washed right after a day of polishing, so there is no rush to get most water based polishes washed out.
