Newb with MF Pads

[racerx909]

I recently purchased some Megs MF cutting and finishing discs with M105 and 205. They seem to be cutting ok but the working time seems to rather short and I'm having problems with the 105 "sticking" to the paint afterwords. I switch to a yellow foam pad using the same amount of product and the 105 wipes off easily. Any advice? I'm using a GG DA on speed 4 to 4.5 with the MF pads and 5-6 with the foam.

Too much m105 on your microfiber pad. You need to clean off the pad so it doesn't "clog" up. Take a brush to the pad or blow it out(with an air hose) in order to clean the pad.

racerx909- Though (as you've discovered) there are some diffs in how M105 berhaves on different pads, remember that the short work time is supposed to be a "feature" and if you overwork the stuff it's hard to buff off.

I'm also seeing the center of the mf pad delaminate a little bit from the foam backing. Is this normal? Astro_ng: I have been using compressed air to clean the pad every other section. I'm sure its still possible that I'm using too much product, but I was trying to only use 3-4 pea sized drops. Does D300 act the same as M105 with the mf pads?

D300 seems to have a longer working time than M105, but I find the M105 cuts much faster once you find the sweet spot for how much to use and how long to work it. I will take a MF towel and rub the heck out of the MF pad between panels and it seems to do a better job cleaning than compressed air. I never really have any problems with the 105 doing this. If and when it does stick, I just use a little QD to help wipe it off.
I also have big problems with the Meg's MF pads delaminating from the foam backing, like completely coming off if I'm really working it hard or on uneven surfaces. I wonder if the Optimum pads do this as well?

.. I have been using compressed air to clean the pad every other section...

Hmmm...I don't wanna sound all and a "section" can mean most anything, but I bet I clean mine out a *LOT* more often than that.

Hey, I find that very interesting! I was using towels to clean my pads until Barry and Kevin (and seemingly everybody else!) told me to try the compressed air and I thought *that* worked better, especially with the MF pads. I'm sure not just pointing out that different people are gonna have different experiences/preferences.

Oh, and I've *still* not had any issues with my Meg's MF disks. Seems I got lucky and received ones from a good batch or something.

I experienced the same problem as the OP last week for the first time. The car I was correcting was being a total PITA. M105 and M205 were both sticking to the panels and were extremely difficult to remove. I was using Meg's MF cutting pads with the M105 on speed 5, and M205 on both LC white and hydrotech tangerine pads also on speed 5.

I have had problems in the past with M105 being tough to remove, but this was the first time M205 was just as difficult. I tried everything I could think of to fix the problem. Less speed, more speed, varied pressure, less/more product on pad, even different polishes. I was cleaning my pads steady with air. Pads were primed. Nothing seemed to help.

Ended up assuming it was his clear coat. A few panels on the car had been repainted a few years ago (hood, bumpers, and rear quarter) and those gave me ZERO problems. All original paint sections gave me trouble. Only positive was the products did their job, as in the correction came out well. Was a very interesting day. I haven't been that frustrated in awhile.
