getting to the outside from the inside

I haven't found the answer to my question... Can I fix the dent under my extracab window from the inside:



I'm not going to be looking for showroom perfect - but if I could get it to look like door dings, I'd be happier than a pig in mud. And, I don't care too much about the paint because I'm going to be re-painting the truck in the next month hopefully.

 

alternate spraying the dent with keyboard cleaner upside down (so it gets cold) and a hair dryer

 

Parking in the sun and using dry ice is 10x easier. But it probably won't work for this. But if I remember right the door skin is accessible from the inside.

 

does that really work? I ran across that technique, but then immediately ran across another video saying it works about as well as a tennis ball does at unlocking your car door...

 

It does but it might not on the more stout door sheet metal. And you can open doors of H2s and H3s with tennis balls pretty easily actually
