I followed the instructions that was sent with my order. I used the first kit and it only filled half the repair on one side of me target. I had to order another kit to finish just one side. It did over flow some on the second kit. I am ok with the foam itself but surprised I had to use two kits for one side. I still had the other side to do, wasn't expecting to use that many units to do one ram. Getting to be pretty expensive for one target.
Easy and actually worked very well.
The repair foam is the way to go to repair your 3-D targets.
