New addition on the Mag-Knight review!
From Andrew Ryder
$20 shipped from Mag-Knight directly. I got the carbon look. It's slicker than the regular colors. Heat up with a hair dryer. Use a real good cleaner on the area and align. Oops, is it not centered? Just rip it right off. It doesn't feel feel abnormal and I've gotten many looks on the carbon look of it. Definitely worth the 20$ for a tank protector.
