Oh boy, you are going to wish you never asked me about microfiber towels!! My supply of microfiber towels is unending! In fact, I would say I fancy myself a collector, like some people collect coins or stamps. I have some in my supply that I have not used in years! I always used Cobras WW for drying (and still do now and then), then graduated to these:
http://neatitems.com/Micro-Fiber-Waffle-Weave-Bath-Towels-24x48.html. But lately I found something even better - http://www.carpro-us.com/microfiber-madness-dry-me-crazy-25-x-17/. These are really great drying towels but I usually use them after a full shampoo when I need all the drying help I can get. It is plusher than a WW of course which is all the better for when I use a drying aid such as AquaWax or Lucas Speed Shine. This kind of towel seems to not only dry better but at the same time it works in the drying aid better than WW. By that I mean I have less streaking. I still like WW for rinseless washes where the water on the panels is not nearly as great.
The best all around towel for just about anything (with some limitations) is my old stand-by towel that I've used for a long time so I have to mention it - Meguiars Supreme Shine. I also like the Griot's dedicated wax removal towels for wax and sealants removal. Recently, I have been experimenting with a new outfit called The Rag Company. I've bought several kinds of towels from them (mostly the plush type) and have been impressed with the quality/price ratio. I think they may still have their free shipping on Fridays which lowers the cost still further.
For the kind of wash you are showing on this video, I like to use these:
http://www.autogeek.net/best-waterless-wash-towel.html. I have half a dozen of them and use them probably more than any other towel in my inventory. For any kind of buffing or QD work I like the ultra plush types and even go so far as the double joined towels such as these Chinchillas which you can find under different names. http://www.autogeek.net/chinchilla-buffing-cloth-combo.html.
There are countless more in my arsenal but these are the ones I go to most often. Oh, I can't forget Sam's cheapo bundled pack of microfibers that are great for the grunt work but I don't usually put them on paint. I am sure they won't hurt if you're careful but I have lots of better ones for that. By now I know you are sorry you asked but there you have it. Keep up the good work on your videos - a picture is worth a thousand words but a video is worth a million!!
