Does the primer color make a difference

Thanks guys. I have always been a mechanical technician. The body work is still pretty new to me but I have fun with it. I just still have a lot to learn. I want to post my restoration of this 74 swinger on the forum, I just have to figure pout how to post pictures from my Android first. I could USSR all the help I can get. I want to find some guys our girls on here that are close to me. I like meeting new car buddies that I can hang out with while building a classic Mopar.
