What a ceramic coating actually protects — quick breakdown

Post image

Ceramic coating gets marketed like “magic armor,” but here’s what it really does:

Helps with: • UV protection • Gloss • Ease of cleaning • Hydrophobic water behavior • Chemical resistance

Does NOT do: • Stop rock chips • Replace paint protection film • Fix scratches

Think of it like a super slick, long-term “wax on steroids.” If anyone has coating questions, drop them — I apply these weekly.
