My shop walls!!!!???!!!! Bite your tongue!
Next you'll be telling me saw dust on the floor is OK.
I'll likely try it at some point. Just don't feel up to it now. I was just using my chop saw and I had to stop. Pain was radiating into my arms and my hands were getting all pins and needles. The thought of hold up my hand to paint is out of the question. I'm going for a nap....
