Eastwood Rivet Setting Tool Bucking Bar for Metal Fabrication

The bucking did work great for other things as well as I'm NOT ready to put the Pannels onto the car as of yet. So I have been using the stuff on other things for now as the bar was a little big for what I needed but it worked great and better then I thought it would for what type of steel rivits that I was trying to smash flat it worked great for that and I didn't even make a mark on the other side the side you would see. But I still can't figure out what the indent in the bucking bar is for yet but it doesn't matter either all I care is that it worked better then I thought it would work and it did and it has different shapes on it. So you can get into different small places with it and it still does really good work on it without damaging the outside pannels if you know what you are doing you won't have any problems with it at all .
