I bought mine, just haven't wanted to do it yet.
I had to do some fender repair on my car trailer and after the welding was done I Herc'd both fenders and the front end where rock chips would happen. The paint on the trailer was kinda sissy and was chipping off and rust was taking over.
The Herc is a little messy and def need to have great airflow and still prob use a respirator.
Wear old clothes and gloves! I should have used a drop cloth under the trailer. I have a few spots on the floor now that will be there a while
