Anybody have any experience with this new line. Supposedly better than their PI II products, at least thats what they told me at the SEMA show.

I use perfect it III compound and love it
 
Since I am not familar with this, apparently new line, how aggressive is the compound. It is comparable to what by Mequiars?

I'm really interested in your opinion here, since you have the three products, that I was told about at the SEMA show that will give me the end result I am after, which we all are after, near perfect cars as possible.
 
I have used the PI-III Machine glaze with good results and have heard good thing about PI-III compound. The PI-III products have been available for over a year, so I am guessing 3M is bringing them to Joe Consumer.



I read in the CMA newsletter that CMA is going to stock the new line which 3m spoke about @ SEMA.

bcgreen - what did 3M say was different about these products from their predecessors?
 
We have used the 3M line for years now. We brought in the new Perfect-it III line when it was introduced. The basis for this line was a product line designed to produce the best results for a clearcoat finish. The compound is quick, and leaves a very smooth surface with a lower amount of swirling the old style compounds. The swirl remover truly works. On our test vehicle we made sure there were visible swirls then used the swirl remover at low speeds with a closed cell foam pad. After a few passes all the swirls had been removed. In order to check for fillers we mixed a solution of 50% alcohol and water and wiped the surface we had done. If this was the normal coverup using fillers we would have cut through and seen the swirls reappear. This did not happen which was great. The product did exactly what is was stated to do. The only item we changed was the glaze which is designed for body shop use being a non silicone product. This is fine for a vehicle that has been painted recently but not for longevity. We use 3M Detail wax from their detailing line which works geat and has a good life. Note that the Detail wax is designed to sheet water rather than bead incase a customer calls you wondering why their freshly waxed surface does not bead. Just tell them that the sheeting action is better for reducing water spotting.

Good luck.
 
Carguy, I really didn't have time to ask them what changed, but only that they did some improvements and that the III line would be better for us detailers.
 
thanks, bcgreen and masterfinish. Sounds like good stuff and I'll check it out.



Masterfinish - I'm confused about your comment re: glaze. I've never thought of a glaze as a long-lasting product. My understanding has always been that glazes were really designed to make a freshly painted surface look better while allowing it to "breathe" until it fully cured. I know that the fillers in glazes make a car look great even when the paint is cured, but because once it is cured it is safe to wax, why do you care how long a glaze lasts?
 
The PI-II fine cut compound uses a crystalline silica & kaoline clay as their abrasive material and the new PI-III rubbing compound uses aluminum oxide and a "trade-secret" dispersable polymer (whatever the heck that means) as their abrasive material.



The PI-III machine glaze uses aluminum oxide and aluminum silicate clay as their compound material.



Also, the PI-III rubbing compound contains oil (as does PI-II), whereas the PI-III Machine Glaze (as well as FI-II) does not contain oil.



I haven't the foggiest idea how all this info I copied from their MSDS's apply to real detailing.

I had to read that 5 times before it even began to make sense...



Comparing 'machine glaze' to the 'rubbing compound'- which is more abrasve?



Thanks!

You are correct in that glaze is short lived. My comment is based on working with customer cars that need a longer finish life which eliminates the use of the glaze product. I would only use it for temorary protection from the elements during a new paint jobs cure period. Any time a customer comes in with a new paint job and asks us how long he must wait to polish I have them ask the painter as there are various cure times depending on what was used, whether it was baked, type of curing agent added that only the painter would know. Based on the that we can do the best job for the customer.

The rubbing compound is definitely more abrasive. It's often used as the first 'cutting' step and the machine glaze is described by 3M as effective at removing the compound swirl marks left over from the initial cutting step.
