Are these mitts somehow different now? I bought 2 mitts from a different company last year, and I swear they were only about $8 each. I'm sure I wouldn't have purchased two of them if they were $50+. I did have some issues with crap getting stuck in them so I planned on buying some new ones, and was doing some latex painting work for a friend and needed to clean some overspray off some stairs, and decided to use the mitts since I was going to get rid of them anyway, and my friend said he would buy me some new ones since they were only about $8. Now I'm ready to buy some more and see that they are $50, and checked where I bought them last year, and they too are $50. But everyone keeps saying they can just rinse these off, and the ones I have didn't rinse off well at all and were pretty tacky. They were hard to store because they stuck to anything I put them in.
My experience with them is that they are fast, but can't get everything that a clay bar can get, so sometimes I would have to hit certain spots again with a clay bar, like road tar and bugs. If I tried to go a little too hard, it would leave some of the clay from the mitt on the paint, and it couldn't get itself off. Luckily it would come off really easy during polishing with a DA.
I guess what I'm looking to find out is if anyone has used the mitts back when they were cheap, and tried out these new expensive ones. I'm not even sure if they had the same name. I believe they were just called clay mitts before, but these being named nanoskin, and quite a bit more costly, I'm guessing they are different. I don't think $50 is worth the mitt that I had experience with, but if these can be easily rinsed and don't get contaminants stuck in them, and you can work the paint hard when needed, I think it might be worth the $50.
EDIT: Just looked at my old invoice and I must have been smoking something because it was $39.99, so not a great difference in price. But it was called "Surface Cleansing Mitt medium gray clay system". But either way, it still didn't seem to be the same as everyone is describing about the nanoskin mitts
