Primered Exterior. Interior color?

[Primered_69]

I'm getting ready to shoot black primer on the outside of my truck because this is the look I like presently. But I was wondering what some of the guys who had done this di to their interior. Dod they primer it or just leave it the original colors?

First let me welcome you to the best truck board on the web.

Most people that are restoring their trucks try to go back with the original color so the inside of the cab is usually left that color.
Primer is really meant to be applied just before the base coat paint, the problem is if left unpainted it will absorb moisture so if you just primmer your truck without painting it you will have to start over when you want to paint it.

I would leave the interior the original color and do whatever you want to the outside.
