My new patina'd RR1 burgundy 1968 Charger ("Ribeye")...mostly original paint

I've read from guys that did the heat and scrape method but I hade no interest in trying that. The needle scaler is loud and dusty but quite effective.
I have a thing with fire though. I don't like it. I wouldn't call it a phobia, I'm just not too comfortable with fires.

There are several things I don't like about scraping...
1. the heat on the sheetmetal
2. dropping molten hot pieces of melted undercoating on your neck/face or down your sleeve.
3. how slow it goes

A propane torch shouldn't be harmful to the metal if you're not getting the metal much warmer than you can stand to touch by hand.
I just don't like fire.   
I'd rather use the scaler. I keep the angle low to scrape rather than to dent!
