6" Megs MF pad blew apart!

I'm on around 20 cars/suvs and no sign that the pads are any worse for the wear. I clean with compressed air (around 40 psi max) after every panel and toss them in the washing machine for cleaning when finished polishing. I let them air dry in open zip lock bags. They seem to clean up like new. I'm using them on a G100 at speed 5 (4780 opm).
 
Had this happen to me over the weekend using the 5" pads on a UDM at 4.5. The pads were primed and blown out with compressed air after each panel and they never felt that hot to the touch. One pad totally separated between the embossed black layer and the maroon foam, the other had 50% separation at the same place as if there's an issue with the adhesive. This was after minor correction work on a small car.
 
If you keep the speed on 5, they hold up pretty well, going higher and using a lot of pressure generates enough heat to soften the adhesive holding the backing on.
 
Scott, often it is the "solvent system" used in the products that breaks down the glue that holds the velcro on.

I always taught that once the job is done with the tool, remove the pad, don't let it set overnight, etc, as the solvents in the product have penetrated and with the pad on the backing, those solvents can't evaporate, so start attacking the glue, etc.

Most of the backing plates do use some glue, but are also "heat sealed" to the plastic, so glue is not the only adhesive in the mix.

Another thing that may contribute to the velcro coming off the foam is the placing of the pad while wet with product, in a plastic baggy when done.

This, again, does not allow the solvent to evaporate and will contribute to the breaking down of the bond of the foam to the velcro.

Not sure if any of these apply, just a sharing of what I learned over the years of using, testing and buying both for distribution under our brand.

I used my microfiber kit for the first time today and the backing started peeling away from one of the finishing discs in the washing machine. I only used the disc for about 15 minutes total. Applied the D301 on speed 3 to a hood and a door. Half an hour later the washing machine had destroyed it. Hard on the wallet...
 
HOT, WARM OR COLD WATER?

Just a question, plus what detergent was used?

What brand was the product?

Your reply may be important to others here.

Hi Grumpy, I used cold water, dawn dish soap as detergent, and this was the meguiars finishing disc. The other finishing disc and two cutting discs were fine.
 
OK, so "quality control" by the supplier to Mequiar's was not on the target that day.

It happens. been there as a manufacturer and such.

What type of washing machine do you have? Usually the older top loader machines with the agitator post in the center will be harsher on pads, as opposed to newer machines that just spin and rock back and forth.
 
Megs should look into the adhesive and Velcro that is on those Detailer's Domain "Uber" foam pads. Those things are bulletproof as far as I know.

Bottom line....

These microfiber discs should be lasting for many cars. How many is many? That depends on a long list of variables. Too many to mention in this post. We have data that shows 200 car disc life at a car auction. And feedback from pre-market testers that describe 50 car disc life, even with aggressive application methods. But if you are getting disc failure in less than 2 cars, something is wrong. That is not the intended disc durability.



Something is wrong: well that could mean two things;



1. Something is wrong with the disc.

2. Something is wrong with the application (or any variable that impacts disc durability.)



1. Meguiar's is investigating a potential quality issue with certain sku's in the microfiber disc line up. You can help Meguiar's understand the scope and specifics of the problem if you report any pre-mature disc failures to your distributor or Meguiar's Customer Care 800 number. As always, Meguiar's will take care of you and replace your product. Your distributor should do the same. Meguiar's is working with a high sense of urgency to isolate and solve any quality issues that may be going on with the microfiber disc. We designed a disc with durability in mind. You should be getting many cars out of it. If that is not happening, we will fix that.



2. Using the disc with durability in mind...



These are the ways you can definately shorten disc life:



* Use any other backing plate besides S6BP, W67DA, or S3BP.

* Let the disc spin on the tool in mid-air, in other words not on the surface.

* Let the discs heat up. (Read below for ways to prevent this.)

* Use too much product (Read below)

* Use the wrong product. The disc was made for certain chemistry, certain products.

* Use too much pressure and speed. (Using the system as directed, you do not need excessive pressure and speed.)



These are the ways you can extend disc life:



* Clean the disc frequently. This thread is full of great suggestions for cleaning. Compressed air is best (with the tool off.)

* Swap discs if you are doing heavy defect removal and the discs are heating up. Going back and forth on discs 1 to 3 times on a car will significantly help to keep discs cool.

* For heavy defect removal, speeds of 4800 to 5800 opm's. Moderate pressure. If the disc stops spinning, thats too much pressure.

* For polishing and waxing, speeds of 3800 to 4800 opm's. Light to moderate pressure.

* Use D300 and D301. Using other products, even M105, can possibly shorten disc life.

* Use a small amount of product. If you are getting foam saturation of the liquid, you are using WAY TOO MUCH PRODUCT. Once the disc is primed, and it does take a fair amount to prime the disc, the disc requires just a small amount to do the job. 2-4 small pea size drops.



Meguiar's sincerely apologizes for any quality problem you may experience with this, or any of our products. Please report them to your distributor or Meguiar's. We will take care of you.



The DA Microfiber Correction System is not that difficult to use, but may have a bit of a learning curve for some detailers. The results a pretty remarkable, all things considered.



I hope the above information on disc maintenance helps...

I still have some of the very first ones I got when we tested them. These things have detailed hundreds of cars and still going strong. I only had a few out of maybe the 100 I have owned go bad. I took them to my supplier they replaced them instantly. No questions' asked.
