Yes Aurora40 I read your post and understand it, no need to get offended..
I was simply stating its hard to compair a paint cleaner with a sealant. I wouldn't use AIO as a protectant period, from my tests/experiance it didn't last longer than a week.
Yes you don't need to use SG with AIO, and AIO can be used with out SG (I use it before all sealants), but I would not use it with out something else as a topper.
I also don't see MPPP being the simmilar as AIO. I have buffed several cars with AIO with good results, but I certinally wouldn't apply MPPP with the PC. There are simmilarities, but in my opinion they are two different products with different designs and goals.
I think we agree on the situation and the which method to use, but are caught up in the verbage.
