PI III Finishing Glaze vs. GEPC

I plan to use something stronger first (I like the Menzerna IP) then finish with a sealant and wax, how would these two compare, if at all? Maybe the PI III Machine Glaze is more like GEPC...



I love the gloss from GEPC, but gotta keep experimenting and the 3M products are available locally, meaning I can pick them up on the way home another product delivery to the door can be avoided. I've exceeded my "quota" of new stuff for the year but have to keep the addiction alive.



FYI, I really love a good carnuaba as a LSP and like the gloss & reflection when using GEPC, whenever I try something that gives a "deeper, wetter look", per detailing boards, my personal preference being what it is just doesn't like it as much. Although a pure sealant as a LSP just doesn't work as well as a good wax over a sealant, for me anyway.
 
I didn't think that PI III MG was all that aggressive. I'm not familiar with the two products you guys are talking about but am very familiar with 1Z products, and I was under the impression that MG was between 1ZPP and MP, do you think that's accurate? And correct me if I'm wrong, but I also thought that 1ZPP was comparable to IP and 1ZMP was comparable to FP?
 
I didn't think it was that aggresive either, on the Autopia aggresivness list the PI III MG is a 2 along w/AIO and other, the Menzerna IP is a 5 alongg with SSR2/others.



I made some assumptions based on that info that apparently are incorrect.



Anyone experience GEPC and PI III FG and can compare the two?

I use both the 1Z line and the PI-III MG regularly, and I'd say your assessment of those products is correct. Haven't used IP, but the MP/FP comparison seems right too. I can't tell any difference when I use FP after MP, for instance (just a squeaky-clean surface instead of a waxed surface).

That "2" placement with AIO is not, IMO, correct. I've used PI-III MG to remove marring that milder products (let alone AIO or GEPC) would never touch. PI-III isn't too aggressive, but it is an abrasive polish that will mechanically remove imperfections. It'll even remove them from hard Audi clear, but it needs to be used with a rotary for that. When I had the WRX, PI-III MG was all I ever needed to remove any marring; it's the only abrasive I ever used on it and that car got driven year round and was washed (none too gently :o ) with a BHB.
 
Thanks for the feedback everyone. Having the correct expectations of what a product will do and will not do goes a long way to being satisfied with how it performs, and ya'll have helped me out.

I think the confusion is because two of 3M's products are rated as a 2 (I don't know anything about these two):



3M PERFECT-IT III TRIZACT MACHINE GLAZE 05930

3M IMPERIAL MACHINE GLAZE 05991



While the MG most of us are talking about is rated as a 4:



3M PERFECT-IT III MACHINE GLAZE 05937
