Not All Primers Are the Same… Here’s What You Need to Know

In this video, we’re spraying epoxy primer on a truck bedside—but more importantly, I’m breaking down the different types of automotive primers and when to use each one. A lot of people think primer is just primer… but that’s not the case. Using the wrong one in the wrong situation can cause adhesion problems, rust issues, or your paint job failing down the road. I go over: Epoxy primer (when and why to use it) 2K urethane primer (high build and blocking) Self-etching primer (where it works—and where it doesn’t) Polyester primer (sprayable filler and when it makes sense) I also explain: When you can apply body filler over bare metal vs epoxy How to prep epoxy before applying filler Which primers should NOT be sanded If you’re a DIYer or just getting into auto body and paint, understanding this will save you time, money, and a lot of frustration.
