Wetsanding with DA polisher

Re: Wetsanding with DA polisher

Interesting stuff. You don't find that you burn through the paint easily if using the polisher to sand? I was just going to do that part by hand.

You can but a couple of comments...

1) Be careful

2) Use a high or fine grit paper, in this example I was using #3000 Unigrit Foam Finishing Discs, very high quality products very safe when used with good technique

3) This is a custom paint job, the paint is thicker than a factory finish and of course before ever starting I did a "Test Spot" to see how easy or difficult it would be to buff out sanding marks and the results from my test spot showed the paint be be very polishable.

Awesome! I've been waiting for Meg's to come out with padded sanding discs for the DA. What speed(s) did you use with the G110?

I did all the sanding and finish polishing using the new G110v2 and it worked flawlessly for both sanding and polishing.

Mike, I thought you said on another forum you polished that out with a Surbuf pad and M105?

After years of typing on forums, one characteristic about my typing style is I choose my words very carefully and specifically and what I typed about the Surbuf pads is that I ONLY used the Surbuf pads with the G110v2 for a small section on the hood, about 20" square.

For the rest of the car I used a Makita Rotary Buffer with a Meguiar's W5000 Double Sided Wool Cutting Pad with M105 Ultra Compound, followed by using the Makita Rotary Buffer with a W8207 Foam Polishing Pad with M205 Ultra Finishing Polish, followed by using the G110v2 with a W9207 Foam Finishing Pad with M205 and then applied M21 with a different, clean W9207 Foam Finishing pad on the G110v2

I also used the new 4" Spot Repair Pads for long, thin panels....







Tilt the polisher a little to lift the leading edge of the pad...





And here's what an ample but thin, well worked-in coating of M21 Synthetic Sealant looks like after machine application using a DA Polisher.

I'm using the Flash to highlight the coating of M21 Synthetic Sealant otherwise it just doesn't show up very well...





And then pulled the car out into full sun and tool all the previously posted shots and these ones as well.

Actually, if you compare equal grits of paper it's actually less invasive and aggressive to D/A sand than it is to hand sand, and the final result gives a more uniform, predictable scratch. In fact, when done properly, 2000 grit D/A sanding is equivalent to 2500 or even 3000 grit hand sanding, it's that much less aggressive. Now, couple that with Meguiar's new Unigrit Finishing Discs with the foam backing and the correct interface pad, and you can quite safely damp sand even over some contours of the paint with very little risk of damage.

Now, none of this is to say you can just go grab some sanding discs, slap 'em on your G110v2 and sand away without worry of problems. We're talking about proper speed, proper amount of water, the correct disc(s) for the process, etc. It's still a skill that needs to be developed and honed, but it's not as aggressive as you might think.

Amazing information as always guys, thank you.

If it's just overspray then clay is the way to go. But sometimes overspray can hold on pretty tight and you need a more aggressive clay. Do you have access to our C2000 Professional Detailing Clay? It's the mild, blue colored clay and it should really speed up the process for you.

thank you sir, meguiars philippines dont sell blue clay, i need to order from states. i think the small particles bond on my paint already, even im keep on claying & using ultimate compound it cant remove i can see it with a flourocent lamp. but when im touching the surface it feels smooth, by the way im using consumer clay kit set
