Color matched Line x

[69ismine]

Hey y'all, I've been in this forum for a while but haven't been active for a while since the progress on my 69 stepper went on hold due to lack of play money. The question I'm dealing with is so I put a spray in liner or not? The truck is in good shape( no rust or major scratches) it's a great driver, but it's nowhere near stock. Am I stupid to put in a line x color match or is it reasonable. I don't have the funds to have 2 trucks so this is my driver. Any advice from more experienced people would be really appreciated.
