Using Pam on a Gas Grill Is there anything wrong with spraying PAM (cooking oil in a can) on real hot grill grates in a gas grill to prevent meat from sticking?

My Dad practices this and I think it's crazy, as it undoubtedly imparts the taste of burnt PAM into the food. I just brush my meat with canola oil before I season and grill it, and this always prevents sticking. Someone help me settle this argument.

Burnt PAM can't be good, right?
Non-stick spray is just oil with a little added emulsifiers to make it extra non-sticky. It isn't any more dangerous when burnt than the oil you apply to your meat.

Spraying oil on the grate will also help season it and keep it from rusting.

The biggest reason not to do it when the grate is hot is that the atomized oil is quite flammable. That said, I spray non-stick spray on the grill and enjoy the pyrotechnics.
