I used those from Korea in bright yellow and blue color and seems like they are creating new swirl mark/scrathes. I can't remember the brand new but I got them from a local Kragen store. Are they suppose to be scrath free?? Any comments? BTW, I didn't wash them before I used them cause of time limitation, is that the reason, I'll give them a second chance(I machine washed them after I used them last weekend) this weekend and report to you guys. I guess Korea need to have better QC on their products. Can I heard something that using fibric softner when wasing MF will destory it? Can I still use the MF after one wash with fibric softner??? By the way, can I use hand to appy Meguiar's #2 instead of buffer? On the bottle, it said it's only for buffer use and no suppose to be used by hand? also Turtle Wax Scratches & Swirl remover? Anyone know if they are good or not? Should I use the #2 before swirl remover? or via versa?
