BC,

Ask around, and see if there is a good pro detailer, or body shop in your area. They might consider showing you the ropes........... for a fee.

Like RP said, at the one day clinics, you won't learn much about the rotary............... if anything.

You could always get a rotary, and practice on another vehicle............. like the wife's, or girlfriend's car!

 

You could always run to the junkyard and buy a dented hood or two... *shrugs*. They make an excellent practice field...
