When Should I Apply Primer?

Use a flashlight to check if your scratch or chip has gone through the factory coating to bare metal or plastic. If it has, you’ll need primer — it’s the foundation that helps your touch-up paint stick, smooth, and last in deeper scratches.

Section 1: How to Tell If You Need Primer

Grab a flashlight.

Shine it into the scratch or chip to see how deep the damage goes.

Look for bare metal or plastic.

If you see either, that means the damage went all the way through the factory primer — so you’ll need to reapply primer before painting.

Pro Tip: Always wipe the area clean and dry before checking — dirt can mask bare metal or plastic.

Section 2: Why Primer Matters

Primer does two key jobs:

Sticks to bare surfaces better than paint does (so it won’t flake off).
Fills deeper scratches thanks to its high solids content, creating a smoother surface for base color and clear coat.

Showroom-quality results start here — a good primer layer is the secret to a finish that looks and feels seamless.

FAQs

Do I always need primer?

In the cases of small chips and minor scratches, if you see bare metal or plastic. Light surface scratches don’t need it.
