How Long Does Spray Paint Last Before Peeling?

Spray paint typically starts peeling after about one year of use. If the car's body paint is damaged, it is essential to have it repaired at a professional paint restoration facility. How to Use Spray Paint: Before spraying, shake the bottle repeatedly by hand to ensure the paint inside is evenly mixed. Prepare suitable sandpaper and lightly sand the surface with a cleaner, being careful not to apply too much pressure to avoid scratches. After polishing, apply a layer of cleaning wax to the surface, followed by a protective wax to maintain its gloss. Precautions for Using Spray Paint: When spraying, aim for a smooth, continuous motion, applying thin coats in a sweeping left-right and up-down motion. Avoid spraying in one spot only, as this can cause drips and ruin the finish. Additionally, do not apply the paint too thickly—each coat should be thin, and allow the previous coat to dry completely before proceeding with the next step.
It's really hard to pinpoint the exact time when spray paint starts peeling off. Based on my multiple experiences tinkering with it, it's heavily influenced by various factors. The worst cases happened when I rushed the job—didn't properly clean the surface, just wiped it with a cloth and sprayed, resulting in bubbling and peeling within a month, like peeling an orange. Under normal circumstances, if you carefully sand off rust and old paint layers, ensure the surface is smooth and free of grease, wipe it down with alcohol or a dedicated cleaner, apply a matching primer before the topcoat, this method usually lasts about a year or so. The environment also plays a key role: leaving it in direct sunlight daily accelerates paint film aging due to UV rays; frequent rain or car washes allow moisture to seep in, speeding up peeling. Don't skimp on spraying techniques—shake the can well and apply thin layers to avoid cracking from overly thick coats. Beginners should practice on small areas and prepare a set of sandpaper and cleaning tools to significantly extend its lifespan. If peeling occurs early, chances are you'll have to start over from scratch.
