6" Megs MF pad blew apart!

So the sad thing is I just got done using a different 6" pad with M105 for taking out a lot of 1500 sanding marks before this and then I swapped to this fresh pad with M205 and then on my 2nd panel this happened:

I was using the Meguiar's BP and was using compressed air to clean the pad. My only problem is I purchased my 6" pads from PAC during their going out of business sale so an exchange with them is unlikely. I contacted Meguiar's about this but have never had to deal with their CS before (which is a good thing given how much Megs product I go through). Aside from this one mishap, these MF pads are amazing, I have yet to use my old Hex Logic or Uber foam pads since working with the MF pads.
 
Anything more than 5 on the GG machine is probably going to create too much heat for those pads. Lake Country pads on the 6" GG have been having a lot of problems too.
 
Ive noticed the Griot's machine can get ridiculously hot, it should have holes drilled in the metal casing to help dissipate heat. I've used MF pads on 6 while heavy 105 compounding before with no problems. This was a fresh pad on a cooled down machine on it's second panel, if I had to pick a polishing moment where I'd expect to destroy a pad, this would've been at the bottom of my list :P.
 
you aren't supposed to go over 4 with these pads. I had the same issue, contacted Meg's and that's what they said.



But I had 2 3" pads blow out in a row using the pc7424xp on 4.

I also noticed the GG gets very hot on that metal part. Then not too long after mine sparked and burned out on me. :doh

I got my replacement today, and continued where I left off, and it didn't seem to get near as hot, which surprised me.
 
what backing plate are all of you using?



Edit nm, hes using a megs backing plate that probably has the holes in it (which are supposed to help dissapate heat.)
 
Speed setting 5 is the limit that you wanna use on your GG with the MF cutting/finishing pad from what others have to say.



Meguiar's recommend speed setting 4 on their very own GG110v2 which equals GG6 3.5~4 also. I've used a cutting pad when correcting my SS Red Toyota at speed setting 5 and never had it look like it was going to blow. The backing on it looks fine also doesn't show the tell tell signs of it about to go like the backing scrunching up.
 
The DA Microfiber Pads have been diligently tested to handle in excess of 180 degrees... and let me tell you, it is very difficult to get a pad that hot.



Get ahold of Meguiar's Customer Service ASAP, and let them know what happened.

I am pretty sure they will take very good care of you.



I personally am sorry that happened to you, and to others. I don't know how many things can occur during the manufacturing process, but I can vouch for the fact that I used dozens upon dozens upon dozens of pads and never could get one to shred apart or delaminate during all the years of testing. Then, I had it happen to me a few months ago.



I suspect that there was a batch that snuck through some sort of issue. And companies such as Meguiar's sometimes make BIG batches. No inside info on this, I just know how much work went into making these reliable. I don't get it.
 
I took the Meguiar's DA Microfiber Class offered by Meguiar's. They recommended that you shouldn't use these pads on the Griot's polisher on a speed higher than 4 for this specific polisher (varies with different machines having different OPM settings.) One thing they recommend is changing pads at least every panel or two and cleaning them frequently.

Thanks for the info! I've always had confidence in the high quality of Meguiar's products so this was a bit of a shock. Looks like I won't be going above 4 with these pads in the future :doh:

Hey, if speed 4 does the job, then why go to 5? :think:



That being said... I have no problem using higher speeds whatsoever. After all, what dynamic does speed affect?



If the backing plate is attached in an even manner, meaning it encompasses a majority of the disc, and the foam has an ample ability to resist shearing into two pieces as the disc is placed under a torque force (Mmmm, just envisioned the luscious creme center of an OREO cookie splitting into two, as its two wonderfully delicious crunchy discs are twisted in opposite directions).



Anyway... :redface:



It is better to use slower speeds if it gets the job done, but don't set your rev limiter just yet.
 
On the speed note, the last car I did turned out better with Flex on 2-3 at the most. Higher speeds could not get the surface to finish as well.



This was 105 and a black foam LC finish pad- soft paint, but the lower speed worked better. Going to do the same with the Griots next time and the MF pads.

I should have been more clear....



I was referring to using more speed in terms of the ability of the disc to handle it.



I was not saying it was better or worse in terms of correction ability.
 
Meguiar's replied back to me and they're going to send me a new one. It is good to see they stand behind their product (not surprised given their good reputation). However, I ruined another disc last night... but this time I was trying speed 4 on my Griot's machine w/M205 on a 5" pad (on the 5" Meg's BP that came with the kit) on my fender (just got done doing the hood and the glue holding on the velcro gave out through about half of the pad). This disc is part of the first set that I got and have used it on 3-4 other cars already anyway so from what I hear its gotten its use out of its life. I'm thinking about fixing it with super glue, but I'm afraid its gonna end up giving some pad wobble or just giving out again.

Are MF pads really meant to only have a usable life of 3-4 cars? I don't want to come off as anti-MF pad but I have several cutting foams that I have used on at least 10-15 cars. They definitely do not look brand new but they are still intact and I have not noticed any drop in their performance.
 
I've heard some people only getting a handful of uses out of them and some people that haven't had a pad fail on them yet. Not sure if there was a weak batch or if it's operator error :-/
