Using Pam antistick spray on the front of my car to avoid bugs

You can try it. I think Pam gets gummy and tacky over time. After a week the Pam might just make the bugs stick more.

I’d rather put an extra coat of a good paste wax on the front of the car. Every few weeks you can wash off the bugs and apply a fresh coat of wax. The bugs won’t stick to the waxed paint, and if they do they will wash off easily.
