first things first, this is my first time using PF2500, and my second time using my Rupes 15.

i was doing a one step polish in a silver Mercedes last night, i had washed and clay'd the car. i used PF2500 on a Rupes yellow pad, spread the product and started working. after 3 passes the product started dusting, so stopped to clean off the product and found clumps of polish on the pad and on the paint. after a quick wipe down i noticed little specs of polish left on the pait (like when removing was before it's fully set). after an IPA wiper the paint wash clean and there wash a good amount of correction. i continued on changing different machine speeds, amounts of product, "priming the pad" with quick detailer. for some reason i could get the product to work for me, after a few panels i switched to FG400 (i have more experience with this product) and finished the vehicle with good results.

am i over working the polish? need to prime my pad? or just using too much?

Too much product. I don't ever prime a pad with Menzerna products.

I do prime the pad, but I use the primed pad, without adding any more product, for my first section (so probably about the same amount of product on first section as Corey's above).

You could be running at too high of speed creating too much heat also. PF2500 seems to stay pretty wet for me throughout the buffing cycle (5-6 section passes). I run it at 4.5-5 on my GG6 (5500-6000 OPM). I typically use a flat LC 5.5" white pad with PF2500...not sure if that is similar cut to the Rupes yellow?
 
Spray a little QD on the pad and it appears too much product. 3-Pea size drops. What you could do is to spritz the pad with a QD when it starts clumping and do not add anymore PF2500. I know Mike Phillips has something about that on the how-to.
 
thanks for the tips, i expected i was using too much by the way it was building up on the pad. i'll use less on the next car and see how it goes.
 
I have had a good amount of experience with 2500. I always prime my pad with a mist of water and then I cover the pad with 2500. That being said I found that certain pads make it dust and clump up like no other. It does not work well with LC White CCS pad for me. So I would try a different pad.
 
Thats strange as I typically always use this product when i'm looking for a good 1 step product that offers very easy cleanup. meaning the product produces virtually zero dust.

It could be a few things. The product is pretty concentrated and you dont need to heavily prime your pad. Overpriming your pad with tons of product will cause dusting with any polish IME. Especially if you prime all the way from the face up onto the side/edge of the pad. Only prime the side if you plan on making use of it. otherwise this causes a ton of dust.

In my experience Menzerna polish's rarely expire if left in a stable environment. ie: not letting them freeze then thaw out. Ive had a few bottles that are from 2008 that I recently got rid of just because i was sick of looking at them. The product was still completely stable and usable.

Its also really important to clean the heck out of your pad with a MF towel once its primed good. Like rubbing deep into the pad and pulling everything out then applying 3 dots and work it again. I do this on just about every 1/2 of a panel. I find this to work really well with any polish and you will really minimize dusting even with compounds.

re: the post above. I agree. This product does work extremely well with a green buff & shine pad. Really good cutting and really good finishing that is on par with just about any ultra fine finishing polish. Its my go to pad on just about every paint system with this product. even very soft repaints.

I tried this method with a light mist of detail spray on a test spot today and it worked great. I was using a Blue Hybrid pad.

I've read that the Menzerna products work best using medium high speeds.
