There has been more than one ocassion on which I got frustrated with some of Meguiar's products so naturally I am not a Meguiar's fanboy.
With that being said, last summer, when I was working outside and heat was driving Menzerna nuts even though I was in the shade guess what saved my day? Meguiar's.
Even more, recently I had a chance to play a little with M105. Unfortunately it was before it was released so I was not free to talk about it even though I wanted to badly as it was making my jaw drop. We were correcting 1500 grit sanding with it as if it was nothing, polish was behaving wonderful, and result was almost LSP ready. Actually, result was so good that some non-perfectionists would call it LSP ready and call it a day. Almost a one-step for "quite good enough" on used car lot beaters. I liked it much more than Power Gloss. Enough that I am kicking myself for not trying to beg out few bottles of it, enough that I went and purchased some as soon as I could, and enough to feel people ought to try it out for themselves.
