Can You Use Ceramic Spray on a Car That’s Been Professionally Coated?
You dropped hundreds (or even thousands) on a professional ceramic coating—and now you're wondering: “Can I use a ceramic spray on top to maintain or boost it?”
Absolutely. In fact, using a spray like Tough As Shell on top of a pro coating is one of the best ways to keep it performing at its peak.
Why Use Ceramic Spray on Top of a Pro Coating?
- Refreshes hydrophobic performance (beading & sheeting)
- Boosts gloss and slickness between major maintenance
- Adds a sacrificial layer to take on daily wear instead of the base coating
- Fills in any minor degradation over time without redoing the full coating
When to Apply Ceramic Spray Over a Coating
- After your pro coating has fully cured (check with your installer—typically 5–7 days)
- During routine maintenance washes (every 4–8 weeks)
- When water stops beading as strongly or surface feels less slick
How to Apply Ceramic Spray Over a Coating
- Wash with a pH-neutral soap like The Super Soaper to avoid degrading the base coating
- Dry completely using the Massive Drying Towel
- Spray Tough As Shell onto a microfiber towel, not directly onto the surface
- Apply in small sections and immediately buff with a second clean Everyday Microfiber Towel
What to Avoid
- Don’t apply over a dirty car—you’ll trap contaminants
- Don’t use on top of freshly applied coatings—wait until full cure
- Don’t use high-pH soaps or degreasers before applying
Is It Safe on Graphene and SiO₂ Coatings?
Yes. Tough As Shell is compatible with most pro coatings—including SiO₂ and graphene-based products. It works as a topper without interfering with the original coating’s integrity.
Testimonial
“My car had a 3-year ceramic coating but started losing its beading after 8 months. I hit it with Tough As Shell after a wash, and the slickness came right back. Amazing booster.” – Luis T.
Top It. Protect It. Maintain It.
Think of ceramic spray as maintenance insurance for your pro coating. It keeps your shine alive, boosts performance, and gives your detailer one less thing to redo next time.
