Nice! Is that lightbar a stock part that comes with the kit? Or did you buy one aftermarket?
It looks like it could benefit from some paint though. Do my eyes deceive me or is that nekkid styrene on the car body? Also looks like you can see the mounting holes for the tail light lenses. Maybe next time hit the inside of those lenses with a coat of silver. That'll hide the mounting pins and give you a nice reflective look to the lenses.
I LOVE how your decals turned out though! If I'd known you were doing a Border Patrol car, I could have sent some reference pics your way. I took a bunch of pics of BP stuff when I was down in Arizona last year.
Nice job!
