Megs microfiber cutting disc disappointent

[takkychan381]

I recently made my first $500 purchase from AG which included a pair of both 5 1/2 inch and 3 inch cutting discs to go along with my griots garage DA. I am very disappointed in the performance to say the least.

I started my process with the mf discs in conjunction with m105 to combat the swirls and minor scratches on my black 2009 chevrolet silverado. I checked my work after about 6 section passes with moderate pressure and found that there had been nearly zero correction of the scratches and a lot of the swirls still remained. I continued on to do another 6 section passes(Eeeek i know) on the same spot with the same results. This time most of the swirls had been removed but all of the scratches remained and so did 'some' swirls. I continued on to do the rest of my hood and both the driver and passenger front quarter panels. By the time i had finished those three panels, all four pads had exploded during use. Now i am stuff with a half compounded truck in my garage, with $500 in supplies and having to wait another week or so to order and recieve replacement pads (deffinitely foam)


I will post pictures as soon as i can, as i am mobile and it is difficult to do.


Also, in no way do i blame Autogeek. This is a great business. I am just extremely dissapointed in the megs mf discs.

Sounds like too much pressure and speed. They are meant to be used with minimal pressure and low speeds at 4 on your GG6.

That may explain it..
I was at speed 5, but i didn't put so much to the point of changing the sound of the motor. Just minimal to moderate.

What did you do to clean the pads? They do need cleaning after each section.

Unfortunately, there is a fair amount of technique in polishing paint. Reading threads and watching videos doesn't always impart enough info for success.

How much product did you use? Did you clean the pads between sections? Did you allow the pad to spin?

Speed 5 will work but you risk overheating the backing plate and pads unless you are using an air compressor to clean the pads after each pass. It sounds like you arm speed was too fast, slow it down and give the pads time to do their work. Light to medium pressure is all you need. MF pads are actually excellent defect killers with 105 or D300, but you have to go slow.

I used about 3 small squirts of product per section. As far as pad cleaner brush, i failed to order a designated one when i placed my initial order. So i used a stiff hair brush on the pads on speed 2 to regain the softness.
My technique is the same as others in the hundreds of videos i have watched. Slow arm speed, 50% overlap, 6 section passes.

Yes they are...but it also sounds like the OP had some RIDS which maybe are too deep to take out.

There are 4 things that I have found that profoundly affect the performance of correction ability with microfiber pads, regardless of brand.

1. The pad must be properly primed. If the pad is not thoroughly primed the individual microfibers will not all be working to level the paint and remove defects.

2. The pad must be cleaned frequently. Compressed air works great for this.

2. Faster speeds will not necessarily equal faster or better results. I use a PCXP and I have found that speed 4.5-5 works great.

3. Firm pressure is key. I try and apply enough pressure to just barely let the pad keep spinning while it oscillates.

How about i upload a vid later of my technique for you guys to critique?
