5 Mistakes That Ruin Ceramic Spray Coatings

A ceramic spray coating like Tough As Shell can protect your vehicle for months — but only if you avoid these common mistakes that shorten its lifespan and hurt performance.

1. Skipping Proper Paint Prep

Applying a ceramic spray over dirt, bonded contaminants, or old wax means the coating won’t bond properly. Always wash with The Super Soaper, clay the surface, and polish with Picture Perfect Polish before application.

2. Over-Applying Product

More is not better. Using too much ceramic spray can leave streaks, high spots, and uneven protection. Apply a light mist per panel and work it in evenly before buffing off excess.

3. Not Allowing Proper Cure Time

After application, the coating needs time to bond. Exposing the car to water, rain, or washing too soon can compromise performance. Allow at least 4–6 hours of dry time, and ideally 7 days before the first wash.

4. Using Harsh Soaps or Chemicals

High-alkaline cleaners, degreasers, and dish soaps can strip away your ceramic layer. Stick to pH-neutral washes like The Super Soaper to keep the protection intact.

5. Ignoring Maintenance

Even the best coatings need periodic refreshing. Reapply Tough As Shell every 3–6 months to maintain top hydrophobic performance and gloss.

Pro Tip – Work in the Right Conditions

Apply your ceramic spray in a shaded, cool environment. Hot panels can cause the product to flash too quickly, making it harder to level and buff off cleanly.
