LOL, Tom can never resist! ;D Can't wait to hear you sing that waltzing song at the next QZ!!!
Seriously, I agree with on on this. WM microfiber cloths are just fine for cleaning and polishing full body paint.
I also question the motives of the article Blueblood is pointing us to. While it has some excellent information on it describing the different MF weaves and their best uses, the idea of having to buy more expensive cloths to get suitable quality must be weighed by the fact that the company publishing that article is in the business of selling expensive MF. When MF first hit the markets, it was VERY expensive at ALL places it was sold, including WM. I did not buy it for that reason. A lot of folks were making good money at RV shows doing amazing demos and selling those cloths at a high price. As you would expect, any commodity like a fabric cloth would eventually come down in price, and it did. I feel sorry for those folks still trying to convince everyone to pay a premium price. I am doing fine with the bulk MFs I buy at WM, Sams, Costco, ACE hardware, etc. I am a firm supporter of MF and use them exclusively now. But I buy them in bulk.
Now I just wish Dry Wash N Guard would become a commodity. Don' hit me Ron! I am a firm believer in that product also, but hate the high price.
I was lucky to buy some half priced bottles from the QZ dealer who was emptying out his load on the last day there.
