Click bait...lol
I think you'd have to be careful with heat build-up. It's easy to cause warping and more work.
Part of the video shows a heat gun measuring metal temp as it goes. Reading shows max of 115-118 degrees, which is actually cooler than these cars can get outside here in Arizona. I have several with top surfaces that have a light, baked rust layer. So this tool is of interest. Cost not much of a factor as it will be spread amongst several projects over time.
It seems to me that a truly effective paint strip involves many different techniques according to what section you are working on, and there is no one-size-fits-all solution. As usual, I get overly analytical about things to the point where I stall on forward movement. Frustrating.
