I think the brown reflective has something to do with carcol colours and the png's colours mixing on that slot, noticed it's only on the front door, hood and fuel cap and I had a similar problem messing around with transparency on the same panels with ticklemyelmo's charger (same base?) A couple months back. None the less still a cool looking skin from all the other screenies try changing the car's primary color to black with the trainer to test it should ALL turn brown
