"We can start today.  I need to order some of the pearl paints but can get started on the sanding.  That will be an all day process."

He grabs a block sander and shows it to her.

"I won't be around for most the day but I will be back by 3 today.  They are waxing the floors at my shop and that is a 6 hour job."

He walks over to the car and starts sanding it, showing her how to do it, sanding 3 or 4 times diagonally in one direction then coming back diagonally the other direction.

"It will take a while to sand the car, if you wanna start with the wheels, I have a sanding disk with a scuffing pad that you can prep them with.  When I get back I will continue with you, that sound good?"
