Struggling with Microfiber cutting discs leaving "marks"

I think I may have to kiss the microfiber cutting discs goodbye as I have about had it with all the fiber marks they leave. They for the most part can be polished out with powerfinish, but 2 things...
1) chasing down every last mark (esp. against edges) is a PITA
2) D300 or M105 finishes down so clean on the DA that I could easily go straight to finishing and skip the medium polish step were it not for the fiber marks.

Has anyone else shared this frustration? I think I am going to start using the Uber yellow pad for leveling and see if I can jump to 85 right after.

I just finished a BMW that left no more haze from D300 that couldnt be cleaned up with 85rd and a green uber, except it needed an orange pad/ power finish step to knowck out the fiber marks...could have saved 8 hours easily had I had a foam compound pad!

 

My guess is that you have been working on cars with relatively soft paint. The combo of D300 and MF cutting disc is my first choice for one steps. Having said that, this combo can be a nightmare like on the last couple of Porsches I did. Under halogens the finish looked mint but once an LED light was put on the paint, WHOA!! I always keep yellow/orange B&S pads on hand just in case the MF cutting disc is a little too aggressive. And yes, after D300 on a B&S Yellow, you shouldn't have an issue going straight to 85RD on a black pad.

 

I agree. THough i have never tried the disc's and have actually been wanting to do so. You can get away with some decent correction using a orange or yellow uber pad and something like Menz SIP. I have finished down LSP ready on a DA with that combo. As stated by Ken it will depend on the paint though as the softer ones will give the same experience that you are having.

 

The type of disc can play a big role in that as well. It seems that using the finishing discs with
compound on softer paint leaves less marring behind.

 

Will have to shout out props though that D300 and the MF cutting disc has some great cut to it. I used to not think so, but Kevin Brown helped me unlock it's potential.

 

Do you guys find that you don't need to use much pressure when correcting with the MF pads? I find them heating up like crazy with my Griots on speed 4.

 

yes, I found that my backing plate for my pc is really hot, speed 4-5, Optimum mf polishing pad with Optimum hyper polish.

 

Glad Mr KBM was able to help you avoid throwing away such a well rounded correction pad, speed and pressure make all the difference in the world. Also the amount of compound used as well as the keeping the pad cleaned througout the correction of any panel you are working on will keep "Jhooks" to a minimum.

 

:thumb: I agree with Bob. Medium light pressure, very slow passes and 2-4 dabs and that's it.

 

Bob, I agree completely. I use my air compressor religiously to blow out the pad after every single pass....I pretty much follow KBM to the T and get awesome leveling (spritzing!) but the J hooks just drive me NUTZ!

They're not a huge issue if time isn't a factor as all they need is an orange pad and 203S to knock out, but I think I could easily skip that step altogether if I were to find a good foam compounding pad to use with M101 to keep true to the name of M101 "foam cut..."
