A ceramic coating is a semi-permanent sealant that protects a car's exterior from damage, giving it a shiny, glass-like appearance after it is applied to your vehicle. It's more durable than wax and typically lasts between two to five years. Depending on the type and condition of your car, having a ceramic coating applied may cost you anywhere from $600 to $1500.

Or you could go the cheap but labor-intensive route — a bottle of ceramic coating costs $50 to $75 — and apply the sealant yourself. If you choose this option, know that for best results, after the coating is applied your car needs to sit for two to three weeks somewhere that is dry and cool. If you have time and confidence to apply your own ceramic coating, the basic steps follow.

Clean your car well, then decontaminate the surface using products made to remove tar and iron filings. Next, use a clay bar and clay bar lubricant to remove anything left on your car. Make sure your car's paintwork has no blemishes because the ceramic coating will seal in surface defects; use a polish remover for light swirls or a compound polisher for deep scratches.
