Well when you get it out the box all you have to do is put some armor all on it and walla looks gloss black...But if you still wanna paint it go with gloss black..I just made up my mind and im gonna color match it this weekend I think it's gonna look badass
It would look good colour matched I think, but the polyurethane flexes A LOT so even the softest paint is going to crack..... Just make sure you use paint softeners and an etching primer and it might last a while.
With a MSP lip... nothing. Line that bad boy up and attach it. Everything lines up perfectly. You can either pull/push it while attaching to make it more even or make it stick out more towards the sides.
