If they still said no they would be signing a notice that I told them of the problem and they refused to have it fixed. I would cover my ass six ways from Sunday on this one. Probably have a third party present to witness everything.

That's what I would do. When I was younger I fixed a lot of cars for friends, neighbors, etc. If I found an unsafe item they didn't want fixed, I made them sign an aknowledgement form before they took the car saying that they were advised of the unsafe condition and refused proper repairs.
