No paint! It's actually a vinyl wrap that I designed - think of it as a huge decal wrapped around the vehicle. It's the same vinyl that is used on airplanes, trucks, floors (advertising) etc.
The jeep is black and the design's background is black so they "melt" together, it's hard to tell where the paint is. I've covered the jeep with it accept for the grill, windshield frame and tailgate. It's very hard to scratch thru to the paint, easy to remove, little maintenace, no damage to paint when removed and it lasts (supposedly) for five years.
Borlo header, no problems with the install (I didn't do it personally, I'm not mechanically inclined - yet). I think it has improved the performance but it's hard to say. My other jeep had very poor mileage about 200 km to a 60l tank, pushing similiar tires, heavier bumper, etc. This one I changed a bit with the regearing, header, KN and throttle spacer. I also downsized to a smaller bumper. My mileage is better, I'm getting about 320 km to a tank now.
Not great but then we didn't buy jeeps for fuel economy.
