While i was working on my slc in the beginning I carried 100 grit sandpaper. I sanded the sharp /rough edges of the car as I worked and sanded all parts as well for sharp edges Only takes a couple of minutes..otherwise your going to see blood spots everywhere.. wondering "where the heck did that come from"? Then you have to check your body twice before you notice the sharp cut on your finger...lol... If they don't get you now they'll get you later...it's all fun and games ....till someone catches a juggler!!!..(omg be safe!!) Just a funny friendly reminder....
