I've really enjoyed reading thru this thread.. I will have three new firearms shortly (M&P 9mm FS, M&P 9mm Shield, and a Beretta PX4 Storm .40 FS) and plan on doing all three with the Simple Green cleaning and then the FrogLube paste method with heat. Since I am new to firearms, I know one important step is cleaning the factory grease out of them, from what others have said, Simple Green works well, is compressed air needed or just a good wipe down with paper towels and rags okay? I would think that the heating with hairdryer process will dry up any additional leftover Simple Green..

Also, seeing as I will be doing three, will it be better to get the 8oz kits versus the 4oz kits?

Thanks for the replies..
