Rust converter

Not rust converter but a easy way I found to remove the under coating is Easy off oven cleaner, spray on let sit 15 min and pressure washer it off.

Interesting. I might have gone this way but I am not blowing the car apart and putting on a rotisserie. I am using an air powered needle scaler and laying on my back, lol. Not to mention it is December in Mn so pressure washer is out for awhile.
