I this could why it happened in your test but I think it's the soft interface combined with just over stressing them in general too.
Say with little to no down pressure to slow the pad down, and no friction from the anti spin shroud, it's allowing the pads to reach a higher speed than they can take.

I've had my washer in since day one and have never had one of these pads fail. I don't have an issue with other MF pads either TBH.
I run my G15/G21 at speeds of 4-4.5. I run my Rupes MKII at speeds of 3-3.5. If this is happening to your pads dial back on the speed and ease up on the downward pressure.

Most of us experience the same issues, but because we love the pads we've made the necessary adjustments.
That said, I understand how it would be frustrating considering how expensive they are. Especially if you didn't see this thread and had it happen to numerous pads. That would stink
The whole point of the tall stroke, is to increase friction as a means to allow for reduction in pressure.
Rupes from day one advocated reduced pressure for their system. I find that I still need some, but not a lot.
Meguiar's on the other hand, states to use moderate pressure. Of course these guidelines are all relative to the individual behind the tool. Moderate pressure to one end user might be light to another. One guy might be 5' tall, 90 lbs, and the other 6' 8", 345... Those two will have their own perspective on pressure description parameters.

What up Kev, love the new spot dude it looks awesome, hope all is well on your end!

Im wondering if this may be something. I have in the past on a specific car had to run it at 6 with MF, but those pads were shot already. At most i will run it at is speed 5 id say 75-80% of the time im at 4.5 while cutting with the G21, and I never use pressure. The only pressure I could think of would be on slightly curved panel, maybe a Cayanne door. As you get lower and it curves it could press the pad against the backing plate causing this issue. But this brings me to my issue with there interface pad that was blown out on 2 section passes. I had to switch back to my CCS pads for the extra cushion.

I think its great they are willing to work with the customer as always, they have great CS. But the reason I am on here is to figure out the problem. No point in having more of what doesn't work(for me). I mean the pads still work reguardless of it being like this. And I feel like they finish down better then the megs MF but for that price I don't want to see it failing.

I could see red foam flying out of the pad. So that eliminates heat, and pressure. <br><br>Any thoughts, or is this just what it is?

And with the below picture showing the edge of the backing plate touching into the center of the foam interface...

The action of any 8mm and larger stroke tool is violent at speed, at least over time. Together with all the other factors, my guess is the damage is being caused by the edge of the backing plate. I've seen this over the years with other foam pads and other backing plates.
I just spoke with Jeff Brown about this and I suggest you give him time to carve out some of his time to sufficiently read through this entire thread and then I'm sure he'll comment.
I don't normally use any company's microfiber pad because when I need to cut fast or cut heavy I use a rotary buffer. I will do some testing of these pads and tools and see what I can find out.
It could be a case for future evolution of the foam formula for this pad and this application. Or a design evolution. By the word evolution I mean that after a product, pad or tool is introduced, after lots of date is compiled tweaks can be made for improvements to improve an existing working product so that it works better.
I don't want to categorically state there's an issue with these pads because like I said, I don't use them. Jeff did say that these pads and this system have been extensively tested and their testing never revealed this problem.
Griot's is a great company with great customer service and Jeff is the real deal when it comes to both hands-on detailing and new product development so let's give him a chance and give him some time.
Thank you....

Re: Boss MF pad issue
I would think this problem would largely disappear with a stiffer foam replacing the red stuff. I do realize that introduces another variable to the "system". And I'm not familiar enough with the system to know what product/pressures this issue occurs with the most, although it looks like it kinda runs the gamut. If it were at the extreme cutting or extreme finishing end, it might be easier to deal with. But in the middle, it's a little trickier.

Oh man, I forgot about the 50's this weekend! Where is the booth at this year? I'll have to make it up there on Saturday if the weather holds out.
