We were shooting a video on how to Machine Damp Sand using Meguiar's Unigrit #3000 Foam Finishing Discs and then how to remove your sanding marks using a rotary buffer and took a moment to show that if you choose, you can also use a DA Polisher with Surbuf MicroFinger buffing Pads to remove shallow sanding marks like those left by the #3000 Unigrit Foam Finishing Discs and a compound.
Just to note, for years now, the question about whether the you can use a DA Polisher, like the Porter Cable 7424XP, the Meguiar's G110v2 or the Griot's Garage ROP to remove sanding marks out of modern clear coat paint has been a hot topic.
While there are a number of factors involved that affect a "Yes" or "No" answer, generally speaking you can remove light or shallow sanding marks out of clear coat finished using a DA Style Polisher with their Free Rotating Spindle Assemblies for drive mechanisms, you just need to use the right pads, products and techniques. Top Coat Hardness is a huge factor when it comes to determining whether or not a DA Style Polisher can remove sanding marks and this will vary between cars.
While the most effective way is still by using a direct drive, rotary buffer with a cutting pad and a compound, especially if you sanding down an entire car, we demonstrated using the Surbuf MicroFinger Buffing Pads with a SMAT product like M105 you can easily remove a controlled sanding mark pattern, in this example, #3000 Unigrit Foam Finishing Papers by Meguiar's were used. Autogeek will have the new Unigrit Foam Finishing Discs very soon. Stay tuned for an upcoming article on this topic.
Surbuf MicroFinger Buffing Pads
This is our project car. This is a restored and mild hotrod 1969 El Camino with a custom basecoat/clearcoat finish. The fit and finish of the panels is excellent and the paint application came out very nice, there are a few leftover sanding marks in the paint and rotary buffer swirls including arc scratches probably from an abrasive particle being trapped between the pad and the paint. Our goal is to remove all the below surface defects and restore a true show car shine.
We moved the car out into the sun where the bright overhead sunlight can reveal the true condition of the paint.
Next we'll Machine Damp Sand the deep swirls and scratches until the surface is flat using the new Meguiar's Unigrit Professional Finishing System.
The section below was sanded using the #3000 Unigrit Foam Finishing Disc on the Meguiar's G110v2 on the 5.0 Speed Setting for about 5-6 Section Passes.
We moved the car back out into the sun to show just how flat of a sanding mark pattern the Unigrit Foam Finishing Papers leave behind and this is because of the Unigrit particle size and distribution of these particles over the face of each disc; two very important factors that make removing sanding marks quick and easy.
A very flat or matte appearance
In person, the paint actually has a sheen to it as it's just a quick step away from a polished look because the sanding marks are so shallow and flat...
Back in the garage under the lights, you can see the Damp-Sanded area and the swirls and scratches in the rest of the paint.
Here are the results after Machine Compounding using the Surbuf MicroFinger Buffing Pads on the Meguiar's G110v2 on the 6.0 Speed Setting with M105 Ultra Compound for about 5-6 Section passes.
We followed this with M205 Ultra Finishing Polish on a W9207 Foam Finishing pad on the 5.0 Speed Setting using the G110v2 for about 4 passes with medium pressure and then two more section passes with just a little more than the weight of the machine to keep the pad flat to the surface. The results you see here are only after polishing with M205, there is no wax or paint sealant applied at this point.
The test section was also wiped clean using straight Mineral Spirits to remove any residual polishing oils.
Note the Dime in this picture carefully placed onto the paint
Close-up to show there are no sanding marks left on the surface, no tick marks or haze. There is a spec of dust just to the lower left hand corner off to the side of the dime that we left there to show just how close we are to the paint when taking this picture. This paint is LSP ready.
