I tore up some LC pads from the back side

I have used these pads on 3 details w/ a PC. A BMW 7 series, GMC 2500 and a durango. They looked fine till I used them on the durango. If I remember right it was on the side panels where I seemed to get most of the damage from.



Am I doing something wrong or are these pads not that durable?

What type of polish, speed and pressure where you using on the pads? were you misting them with water or QD at all ? I know that I had a similar issue with the old version of Lake Country pads but they are suppose to be improved since then.

Menzerna IP with the orange and FPII with the white. Start at 4 and end up at 6. Moderate pressure IMO.



Looks like the backing plate is too big and cutting into the pad.

I'm using the backing plate from coastal tool that came with the PC. I measured it and the velco backing on the pads, they both seem to be the same.
 
It does look like the backing plate is cutting into the pad. What is the size of your pad and backing plate. Also, I personally never take my PC up to 6. 5 is the max I would use with the PC when applying moderate pressure. If it requires more cutting, I bring out my trusty Makita 9227c rotary to get the job done. There are just some things a PC can not do or was not meant for.



Most pads used with the PC will not outlast pads used with a rotary because of the random oribtal action (jiggle) from the PC. The tension on the adhesive on the pad will break down quicker when the PC is used in excess of 5 on the speed dial when using any type of pressure. It's the nature of the beast, it works great when used properly. But there are it's limits.

Did you break the pad it in at all, it may help some. Lake Country has a suggestion on for breaking their VC pads in. I have listed the link below with a direct quote from them. it may help you out. maybe the pad was too dry and the backing took the abuse ? just a thought, especially with a more agressive polish. this damage looks exactly like what I had with a couple of their old flat pads. I have followed this seasoning method and have had no issues with them since I started doing this, the first time I used them. I am using the 5 inch backing plate and had the same problems so maybe this tip will make the pads wear a little better ?

here is the part talking about seasoning

You just mentioned using your advanced pads in a flat position after "seasoning". What is seasoning?



A: Seasoning refers to breaking in a pad. If you were to apply polish to a body panel, place an Advanced, VC Pad on the surface and turn the machine on it would be very squirrelly or difficult to control. This is due to most of the pad being "dry". To season a pad, lightly mist it with water, slightly raise the back of the machine so you are working with the top 1/3 of the pad. After polishing for a minute or two the pad will become more evenly saturated with product and actually become softer from heat build-up. At this point, you can safely transition from the tilted up to a flat polishing position. Every time you put a fresh, Advanced, VC pad on your machine you should season it for a minute or two before "flat" polishing.

Then it's likely that the size of your BP is the problem. When pressure is applied and the PC is jiggling the portion of the pad that is just outside the velcro area meets the "hard" BP causing the ring that you're seeing on your pads.
