how is the MF wash mitt compared to the sheepskin wash mitt? I know the durability of the sheepskin one is less but which mitt would have lesser chance of causing swirls?

+1 on the leaf blower to dry car, been doing that for a while now.

 

I like your mitt question.

 

I've used both sheepskin and MF and prefer the MF by a wide margin. Personal preference. MF is a lot more durable. I can't say which is more or less likely to cause swirls. That's less on the equipment and more on the technique.

 

I'm going to try the mf mitt next time.

 

Light dust: Blackfire waterless wash and about 6 MF's and then afterwards spray with BF poly spray.
