If you take one thing away about ceramic coatings, make it this: the prep is the job. A coating bonds to your clear coat and locks in whatever condition it's in — every swirl, every water spot, every speck of bonded grime. Do the prep right and you get years of gloss. Skip it and you seal the flaws in for good. Here's how to prep properly, step by step.
Step 1: Wash and strip
Start with a thorough wash using a pH-balanced shampoo like LATHER to clear road film and loose dirt. If the car has old wax or sealant on it, you want that gone too — a coating won't bond through it. A dedicated stripping wash or a clay step (next) handles the leftovers.
Step 2: Decontaminate
Washing removes what's loose; decontamination removes what's bonded. Two parts:
- Iron removal. An iron remover dissolves the embedded brake dust and industrial fallout that a wash can't touch.
- Clay. Run a clay bar or clay mitt across the paint to pull off bonded contaminants. Feel the surface afterward — it should be glass-smooth.
Step 3: Correct (if you want the flaws gone)
This is your one chance to fix swirls and light scratches, because the coating will lock in whatever's there. If a flawless finish matters to you, machine polish the paint now. If you're doing a lighter DIY job, you can skip heavy correction — just understand that any swirls you leave will stay visible under the coating.
Step 4: Wipe down the panels
Polishing leaves behind oils that can block the coating from bonding. Wipe every panel with a dedicated panel-prep spray (or a suitable IPA wipe) so the coating meets bare, clean clear coat. This step quietly makes or breaks adhesion.
Step 5: Final check, then coat
The surface should be clean, dry, smooth, and contaminant-free, and you should be working in a shaded, dust-free space. Now you're ready to lay down the coating — walk through it in how to apply a ceramic coating at home. And for the errors that undo good prep, see 5 ceramic coating mistakes that ruin your results.
Where Detail Labs fits
LATHER is our pH-balanced foaming shampoo — the right first step because it cleans without leaving residues behind. Once the paint is prepped, BOND·9 is the coating that rewards the work: 9H hardness, 24 months of protection from a single application.
Frequently asked questions
Do I need to clay bar before coating?
Yes. Even paint that looks clean has bonded contaminants a wash leaves behind. Claying (after an iron remover) gives you the smooth, clean surface a coating needs to bond to.
Do I have to polish first?
Only if you want existing swirls and scratches gone. The coating won't hide them — it locks them in. Polish now for a flawless result, or accept the current condition before you coat.
Can I coat over old wax or sealant?
No. The coating needs to bond to bare clear coat, so strip any old wax or sealant during prep. Leftover protection is a common reason coatings fail early.
What's a panel wipe?
A quick wipe with a prep solution that removes polishing oils and residue, leaving a clean surface for the coating to grip. It's an easy step that has a big effect on durability.
