Can You Apply Ceramic Spray in the Sun?
Ceramic spray coatings work best in the shade—but what if you don’t have that option? Here’s how to safely apply ceramic spray in direct sunlight.
Most detailing guides will tell you to avoid applying ceramic spray in the sun. And they’re right: heat and sunlight can cause the product to flash too quickly, leaving streaks and haze. But with the right techniques, you can still apply ceramic spray outdoors on a sunny day without ruining the finish.
Why Sunlight Makes Application Tricky
When paint is hot, ceramic spray dries almost instantly. Instead of spreading evenly, it flashes on contact, leading to:
- Streaks and high spots
- Uneven gloss
- Wasted product
- Difficulty buffing to a clean finish
How to Apply Ceramic Spray in the Sun
- Work Small: Coat half a panel at a time instead of the whole car.
- Use Less Product: Just 1–2 sprays per section. More will flash and streak.
- Spread Quickly: Use a short-pile towel like Everyday Microfiber to spread fast.
- Buff Immediately: Follow with Softer Than Soft Towels to remove streaks.
- Work Top to Bottom: Start on the roof, then move down, since upper panels are usually hotter.

Common Mistakes to Avoid
