How big of a jerk am I? Or are you?

dont answer just yet but if you have time for a long winded question, read on.
At the moment, there is a small film crew in my backyard filming a backyard remodel internet show. My sister in law is head of this company that makes these little promotional videos for this home remodel website.
I work in this industry doing lighting on commercials, tv shows etc so I know the havoc a film crew can wreak on someone's house. But since it's for family and they are only in the backyard, I agreed as it would really help out my sister in law. It's a crew of only about eight people and we supposedly get about $1k in patio furniture for our trouble. The wife wanted to do it sooooooo........here we are.
The only worry here is that my 65 belvedere lives in the driveway in front of the garage, behind the house. My only stipulation in allowing these guys in our yard was that my car not be touched. At all.
So Friday they came and dropped off tools, cleared off our patio etc and were set to start filming today. I got off work early today and peered out the back window to check out the operation and was a little unnerved. A couple of hipster dudes leaning on the car. Lots of people's personal belongings on my car. And some heavy duty extension cords(stingers) across the hood. That's when one of the hipster dudes dragged the cord across the hood of my car. I am now over it, officially. Lol.
Now bear in mind that my car doesn't have fancy paint or anything but I have worked hard on it and I really like the car. It's heavily patina'd but has a near perfect grille, rechromed bumpers, really nice original tinted glass, nice brightwork, etc.
Right about then my wife came home and I told her we(she had dealt with them exclusively up to now) needed to talk to these folks about the car. We politely told them that we didn't want the car touched and reminded them that we had stated that initially, as well. Not to mention, they could run their wires UNDER the car quite easily.
The producer people were super nice but the kids on the crew looked at me like I was from mars. I understand that my car looks like junk to a non car person but I do have quite a bit of money in this thing. I felt stupid for a minute but then I thought to myself, "hey screw that! It's my damn car and I don't want anyone messing with it!"
So my question to you guys is, what is your policy about people touching your car? And, obviously, I know you guys don't want anyone touching a car with nice paint, etc. I have included a picture of the whole operation so you can see the condition of the car and the remodel operation. Do you get pissed if someone leans on your driver/beater?
I was just thinking about this after these guys left and wondered what you guys thoughts were.

Damn kids!! Get off my lawn!!!:lol:
Here is a reference photo. And yes, there is a porta-John next to my car.

They may not have gotten the memo even if you said it before.
They looked at you because millennials are turning away from car ownership.
(Look it up).

I don't seem to have problems with people touching my cars that I know of.

To answer your questions.
1. Don't touch.
2. I would get irritated. Not pissed. If no damage.
It does show a lack of respect for other's property.
Now, car door dings and shopping cart scratches equals pissed.
