Sooo...
Sunday morning I spray painted for about half an hour or an hour (just two cans). Obviously it wasn't half an hour straight of painting as I needed to take a break for my poor fing-y. It is now Wednesday- 3+ days later.. and the tip of my pointed finger is still numb/tingly. I poked at it with nail clippers.. I got nothing..
I had this problem once - get the gripper thing you can attach to the can so you don't have to push down with your finger. Here is what I mean...you will thank me :)
