The gelcoat on my new(used) boat was horrible. I tried using heavy duty rubbing compound by hand with no luck. I saw it suggested to try one of the foam wax balls you can get at autozone. These are the kind you attach to a drill. Thought Id give it a shot. Put it on my cordless and try it out. Boat cover was on but I was just going to try out one spot to see if it worked. The cordless just didnt have enough power. SO, I went and pulled out my brand new electric hammer drill. This thing is a beast. Put the ball on and away I went. Man does that thing spin fast. It was getting really shiney! So I wanted to do a little more. I was blasting away, happy my boat was gonna look so good. WELL, it only takes a split second to go more bliss to screaming agony. Since I left my boat cover on, the ropes that go under the boat and tie onto the other side of the cover to hold it on were still there. I got a little to close and the big foam ball grabbed the rope. This drill spins like a demon. Its heavy to so one hand was supporting the weight of in on the body with my fingers only inches away from the chuck. The rope spun around my fingers and kept going. I let off the trigger but it doesnt stopp spinning instantly, it slowly winds down. I closed my eyes as my fingers were being strangled and twisted in the rope. In my mind I was screaming NOOOOOOOO. It hurt so bad. It finally stopped. I didnt want to look. I knew my fingers were twisted off and meat and bone would be sticking out. I pried my eyes open(the tears made it harder) and looked at my hand to see three fingers strangled with rope and bright purple. THEY WERE STILL ATTACHED THOUGH!! I reverse the drill and slowly backed off the rope. They were blood bruised and screaming at me. It went inside and iced them good. I thought one may have been broken but just iced them good and thanked the heavens I still had all my fingers. Its been a week and I still have no feeling on the side of one of my fingers and they still feel very sore. I was lucky though. Hopefully reading this, it may make someone think about this if they ever decide to do something stupid like I did. I just didnt even think about it. But I can guarantee you that next time Ill take the ropes off first
