After seeing many ppl swear by MF pads, I picked up some and tried the first time with my GG6 polisher and 5 inch LC backing plate. The pads used are Meg's 5 inch cutting pads. However there are the problems I had with it:
1\ Pads are heated quickly: usually after around 4 section passes. I know this is prob because of the LC backing plate.
2\ Lesser correction than LC hydro pads. I 2500grit sand down an area, did a 50/50 with Microfiber and LC hydro pads. Used Megs ultimate compound. I was ready to see the amazing correct ability of MF pads. However with 4 section passes, MF didn't remove all sanding marks, actually MF pads left a lot of remaining sanding marks(4500-5000rpm on GG6). Either Cyan or Tangerine gave an almost perfect finishing around 2 passes.
3\ products dry way too fast with MF pads? I only tested the ultimate compound, which drys slower than M105. With HT pads, I have no problem working the chemical for 6+ passes, and still be able to remove with ease. With MF pads, after around 3-4 passes, I HAVE to use IPA to wipe down the dried chemicals on paint. The comparison is made on the same panel, same time of the day, so the temperature should be the same. Both MF pads and HT pads were primed before using
4\ Lose fibers: not a lot, but still noticeably, MF pads lose fibers now and then.
5\ Foam quickly worn out: I end up using the MF pads to do half of the trunk. After that I notice the foam already started to wear out. Although it's not significant and the pads are absolutely usable, Still it annoys me a lot.
6\ Hard to make the pad rotate? with 4500-5000rpm on GG6'', I can make the MF pad rotate with low pressure, but with medium pressure, the pads stopped rotation immediately. To compare with, with LC HT pads, not a single problem when using medium or high pressure.
All in all, that's all the problems I found with Meg's MF pads, I wonder if I used totally wrong technique, or is UC totally incompatible with the MF pads(haven't tried M105 yet)? so here is the way I used the pads:
Polisher: Griot's garage 6 in polisher
Compound: Meg's Ultimate compound
MF pads: 5'' cutting pads, 4500-5000rpm, primed, light pressure. Pads rotated most of time
LC HT pads(both Cyan and Tangerine), 5000rpm-6000, primed, medium pressure, pads rotated all the time
Feed back please
