I bought this guys last one. All in all he does good work. I am happy with mine. Though the lettering "valve" had unremoved/polished flash between the letters that was unnoticeable in the pics he posted. Ask for closer pics of the letters before you buy to make sure youre happy. Its hard to get it there we know!! And nope, it won't turn blue. Mines still blingin' and its been on since mid summer! I coated mine in blue magic to protect it even more!
