Meguiar's Microfiber DA Correction System with Griot's Garage 3" Mini Polisher
Since thin pads rotate better on tools that use a Free Floating Spindle Assembly, a number of people have asked how the new 3" Microfiber Discs work on the Griot's Garage 3" Mini Polisher? So I did a little testing and below are the results...
First I dampsanded the paint using Meguiar's Unigrit S6F3000 Foam Backed Finishing Discs
Unigrit Discs leave behind a shallow and uniform sanding mark pattern that buffs out quick and easy with a wool pad and a compound on a rotary buffer. This is the traditional way of removing sanding marks.
The new Meguiar's Microfiber DA Correction System is not intended to be used in body shops, nor is it a replacement for a traditional approach to remove sanding marks using a rotary buffer, a wool pad and an aggressive cutting compound.
I merely used #3000 Grit Sanding Marks as a way of doing some controlled testing so I would know the depth of the defects being removed.
In the real world, when a person is detailing cars they are removing random swirls and scratches of varying depths. In most cases the shallow swirls and scratches will be removed first leaving behind only the RIDS or Random, Isolated Deeper Scratches.
In this type of test since all the sanding marks are the same depth, the goal is 100% removal AND to test if the 3" Mini Polisher will work with the thin microfiber buffing pads.
On the 3" Griot's Garage Mini Polisher is a cutting disc that has been primed with the D300 Correction Compound and now has 3 pea-sized drops of product on it.
Speed setting was 6 and about 8 section passes were made twice, the second time I cleaned the pad and added fresh product. The tool was able to maintain pad rotation as long as I make sure it was flat to the surface and didn't push down too hard. I also misted some water onto the surface anytime the product started to dry, the water helped increase lubricity and this made it easier for the pad to rotate.
After the second section pass I wiped the residue off then wipe the surface with some IPA and had about 99% defect removal with just a little haze left in the paint.
Next up some D301 Finishing Wax, it was much easier for the 3" Griot's Garage Mini Polisher to maintain pad rotation with this product.
Time to remove the tape and check out the result...
I wiped off the residue and then re-wiped with the IPA to see the true results,
Keep in mind, this is a repainted hood and all paints will react differently.
Next up I tested the Bug Sponge to see if it would work to clean the pads on the 3" Griot's Mini Polisher and it did work but like when you're polishing, you need to keep the face of the pad flat against the Bug Sponge as any extra pressure on just an edge of the face of the pad slowed down pad rotation.
So did the 3" Griot's Mini Polisher work to remove defects with the new Microfiber DA Correction System?
Yes, but it would be faster with a normal size DA Polisher with a 3" backing plate or with one of the air tools that go with the system.

- Sanding Marks 100% removed
- No Swirls
- Light Micro-marring left in the paint
