Most of the detailing work I've done in my life involved me driving to a client as most people wont' take their "baby" to you if you live very far away.
For example a few years ago I buffed out Sniper, a 1954 Plymouth Savoy built by Troy Trepanier and designed by Chip Foose and there's no way the owner was going to drive Sniper to me. So I had to drive to the Sniper. Sniper is now a part of the Petersen Museum Collection.
Taken after I removed the swirls... I also taught the guy driving it how to use a Porter Cable DA Polisher and have pictures of him working on this car which is kind of funny as he's really tall and the car sits really low to the ground. Cool guy. Also owns a 1967 Shelby Cobra, (real one) and a few other authentic race cars.
Back to the point, it already takes a long time to buff out a car and at the end of the process I can't hang around for 12 hours to pass so I can apply a second coat of anything and I always apply to applications of the LSP of choice as a best practice.
So I apply the first application, allow it to dry and then wipe it off and then find something else to do like dress the tires or detail the car where any painter's tape was applied and then apply the second coat after about 30 minutes. Allow this application to dry and then wipe it off.
Tell the owner now that if he touches the paint in the wrong way he'll probably put a scratch or mar into it, give them a few tips on how to wash and wipe and wax the car and then leave.
Don't make things any more complicated than they have to be, ESPECIALLY for daily drivers.
