Coating Aftercare

The First
48 Hours

Your coating is applied and cured in our shop, but it keeps hardening after you drive away. For the first 48 hours, keep it away from water. That means no washing, and if you can help it, no heavy rain.

This is the only part of coating ownership with a hard deadline attached. After two days, the coating has done the bulk of its curing and you can move on to the normal routine below.

Everything after this point is maintenance, and how well you do it is the difference between a coating that lasts seven years and one that quietly stops working in three.

How to Wash
a Coated Vehicle

A coating does not mean you stop washing. It means washing gets easier and matters more.

1

Hand wash, or touchless only

Hand washing with a clean microfiber mitt is ideal. A pressure washer or a touchless automatic wash are both fine. Anything with brushes is not.

2

Use a pH-neutral shampoo

Harsh detergents strip coating performance. Stick with a pH-neutral formula. We use Shampoo+ in the shop and it is what we send customers home with.

3

Dry it immediately

Do not let it air dry. Use a clean, high-quality drying towel to stop water spots before they form. This is the step people skip and the one that shows first.

4

Top it with a ceramic booster monthly

A monthly application of Amplify keeps the water beading and the surface slick between visits. It can go on after every wash if you want, but monthly is the point where it earns its keep.

TWO HABITS WORTH BUILDING

Park in the shade when you have the option. Prolonged UV and heat exposure is what ages a coating between refreshes. Down here that is most of the year, so any shade you can find is worth taking.

Deal with bird droppings and tree sap within a day or two. Both are acidic and both will etch into any surface given enough time. The coating slows that down. It does not stop it.

Six Things to Avoid

None of these are hypothetical. Every one of them is something we have seen shorten a coating that should have lasted.

Brush car washes

Spinning brushes cause micro-scratches and will degrade the coating over time. This is the single fastest way to undo the work.

Dish soap and harsh chemicals

These strip the coating's hydrophobic layer and can cause premature failure. Dish soap is designed to remove grease, and it does not know to stop at your paint.

Letting water dry on the surface

Standing water leaves mineral deposits that can etch and stain the coating. On the Gulf Coast this happens faster than most people expect.

Wax or sealant over the coating

These products sit on top of the ceramic layer and interfere with it. They reduce its effectiveness rather than adding to it.

Abrasive compounds or clay bar

Abrasives will remove the coating. If your vehicle has contamination that needs pulling out, bring it to us instead of working on it at home.

Ignoring bird droppings or sap

The longer they sit, the more likely they are to cause permanent etching. A coating buys you time here. It does not buy you unlimited time.

The Maintenance
Visit

Every six months your vehicle comes back to us. We inspect the coating panel by panel, detail the vehicle, and boost the coating so it goes back out performing the way it did on day one.

This visit is what keeps your 7-year warranty active. Skipping it affects your coverage and shortens the life of the coating, which is why we are direct about it up front rather than burying it in fine print.

It is also the point where we catch things early. A coating that is starting to struggle on the hood is a cheap fix at the six-month mark and an expensive one two years later.

WHAT WE USE

We do not sell products, but we get asked constantly what we use in the shop. The short list is a pH-neutral shampoo, a ceramic booster, a good drying towel, and an interior cleaner that does not leave a shine behind.

We put the specific products on one page so you are not guessing in a store aisle. See what we recommend, or download the full aftercare guide as a PDF to keep in your glovebox.

Not Sure About
Something?

If you are unsure whether something is safe for your coating, ask before you try it. We would rather answer a question than correct a problem.
