I've got a little bit different answer than most. I've been in business for years and years but not detail biz, so take that into consideration. I suggest that after you get a good look at his vehicle and his products that you propose a compromise. Use some of his products, ones that you don't feel you're taking as much a risk with, along with some of your own you're more confident in. That way he feels he's contributing and you don't go in completely blind. Some customers just got in their mind they want things done a certain way. But make sure you get covered for your trouble a minumum $50 per hour (or even more) as has been stated. And don't subtract anything for using some of his products rather than your own.

Through the years I've had customers with idiosyncrosis and they're not all necessarily going to jerk you around. Some even offer more money because they realize they're making you go the extra mile.
