Played with a COOL new Eastwood tool today. Worked GREAT!

I know this new tool has been out for a while, but I used it for the first time today. I am helping a friend restore a 56 Studebaker Powerhawk. We just finished scraping the old undercoating off of it, and this new tool will take the rusty surface down to shiny metal in no time. The time to get from the before picture to the after one was 6 minutes.View attachment 1715342704 View attachment 1715342705 View attachment 1715342706
Did you notice if it put much heat in the metal? I'm wondering how it'd work on a roof without warping the metal.
