Do You Need to Use a Panel Prep Before Applying Ceramic Spray?

You’ve washed, maybe clayed, and your car is looking clean. But before you apply ceramic spray, a new question pops up: “Do I need to use a panel prep or IPA wipe before I apply this?”

Short answer: Not always—but in some cases, yes. Let’s break down when panel prep is necessary, when it’s optional, and how to do it the right way before applying Tough As Shell Ceramic Spray.

What Is a Panel Prep?

Panel prep (sometimes called "panel wipe" or "IPA wipe") is a solution that removes:

Oils left from polishing
Residue from soaps or cleaners
Light contamination that affects bonding

The goal is to leave a squeaky-clean surface that allows ceramic spray to fully adhere and bond properly.

When You Should Use a Panel Prep

You just polished the car (polishes contain oils that can interfere with bonding)
You’re removing waxes or sealants before applying ceramic
You're unsure what's been applied previously
You want maximum longevity and performance

When You Can Skip It

You’ve done a proper wash and clay, but didn’t polish
You’re maintaining an existing ceramic layer
You’re spot-treating or reapplying every month

For casual use or frequent reapplication of Tough As Shell, panel prep is helpful—but not mandatory.

How to Do a Proper Panel Prep Wipe

Use a 70% isopropyl alcohol (IPA) mix or a dedicated panel prep solution
Spray onto a clean microfiber towel—not directly onto the paint
Wipe the panel evenly in straight lines
Flip towel and follow up with a dry pass to ensure no residue remains

What Happens If You Don’t Use Panel Prep?

If your surface has polishing oils, waxes, or unseen contaminants:

Your ceramic spray may streak or haze
It may not bond evenly, resulting in patchy beading
The durability of the coating may suffer
