It shouldn't cost you that much more from the body shop to do the stripe while their doing the paint job....just ask. Pearls are fun to work with. I did a CJ7 Jeep for a guy in Bright orange then put 4 coats of gold pearl over that and followed with 3 coats of clear.One way yopu looked at it ,it was orange and when the sun hit it just right it was a light tangerine looking pearl. Got a load of compliments off that Jeep!!. Just make sure whatever they do they can re-do if you have an accident! Like I said ....pearls are fun. Good luck.....
