Better results with 3" mf pad vs 6" mf pad

[jvamagic]

I wetsanded my car with 1500/2k/3k and went at it with menz fg400. I started with a MICROFIBER ORANGE CUTTING PAD 5.5" and didn't really like the results (had to go over twice or more). This using a PC 7424xp ( I have a dewalt 849 but don't quite trust myself).

I ordered 3" mf cutting pads for the smaller sections and saw a difference from the 5.5" pads. It cuts so much better/faster. Is it because of leverage etc..or because the Meguiar's pads are that much better? The 3" disc don't have much padding so I assume it builds heat quickly which cuts better??? Just trying to figure this out for future reference.

I finish with menz 4000 with a white pad and it comes out pretty nice if I may say so myself. I will post photos when I'm done.

I have not tried CG's pads, but the combination of thinner backing and smaller pad will both contribute to additional cut.

For my style, the Meg's MF cut better than B&S (not sure if B&S makes those pads for CG though.

Same Power applied to a much smaller footprint = defect killer

Thanks for your replies....will adjust accordingly.

As a previous poster noted, assuming the power output of the machine is fixed (that you are using the same speed), that power is being distributed over a smaller area (7.1 square inches vs. 23.8) so you are potentially doing ~3 times the work to your smaller area. It's just math. The downside of course is you are only covering 1/3 the area so it will take you longer to get done.

I just stick with Meguiars pads, after all they came out with them for automotive use first.

So if I purchase the 6" Meguiars cutting disc's it will not be much different than when using the 6" chemical guys cutting pad? Have another DIY project and it's my SUV.

I really can't speak to the CG pad, but it's just physics that you're going to get better correction with a smaller pad. Why don't you buy the 5" Meg's discs? Or is your backing plate too big?

I have a 5" backing plate. Sounds like I should go with a 5" Meg's disc.

Since you're trying to clean up wetsanding maybe you should go for the XC disc:
