I was bored yesterday and I had around 60-70 paintballs that had been subjected to water for about 6 minutes. So I got a toothpick and puch a hole in every paintball and emptyed the fill into a plastic cup. Then I heated it up in a pan for about 4 minutes. Then I put my bolt in it just to see what it'd do. After 4-5 minutes I pulled it out and rinsed it off with water and a paper towel and VOILA, my bolt was shinier and didnt have wear on it! Dont ask me what made me do it...or why it got shiny...maybe cause the vegetable oil in paint fill.

i think it's just because you put it under intense heat ... aluminum is made from chemicals ... and you probably let some of them seep off into the water ... i dunno if this is the greatest idea though ... the bolt isn't getting even amounts of wear
