I'm sorry, guys, and I know it's only my opinion. But you have the perfect opportunity to make that truck look Beautiful. Then you decided to just clear coat over the junk.
Where are you? I have a 68/69 grill I will trade you for your grill if it is in good condition and I like the look with the gloss over the original color.
Honestly the truck really isn't worth it. Would need extensive body repair, to put a nice paint job on it correctly. The customer is going to use it for his diesel repair business and likes the original look
