Bill,
Yes Craig is set up to do 12 ga. dent removal.
He did remove a very small dent in my right barrel.
Craig is away at his camp in the mountains this weekend.
I’m sure when he gets back he will be able to give you a more detailed answer.
LOL And don’t worry Bill, I wont spill the beans to Ms. Wanda on FB.

I very well know about wives & buying guns. Like vinegar & water.
Good luck, and after the dust settles and ya have the new baby in hand,
take lots of pictures for us to drool over.
