How long after crystal coating can the car be exposed to rain?
2 Answers
Crystal coating requires 24 hours before the car can be exposed to rain. Avoid wiping the paint surface for three days and refrain from washing the car for one week. The crystal coating process includes: 1. Covering the windshield, license plate, and gaps; 2. Using polish and ultra-fine swirl remover to eliminate fine scratches on the paint; 3. Degreasing the car's paint surface; 4. Polishing the paint with a professional crystal coating cloth. Benefits of crystal coating: 1. It isolates the car's surface from external elements, preventing oxidation and protecting against acid rain corrosion, thereby extending the paint's lifespan; 2. Makes it easier to clean dust, dirt, and other debris from the car's surface; 3. Reduces damage from external forces; 4. Enhances resale value.
Whether you can expose your car to rain after ceramic coating mainly depends on the specific product and the weather during application. Last time I had mine done in summer, the technician emphasized absolutely no water contact within 24 hours, and normal use was only allowed after three days. This is because the coating needs time to cure - it remains in a soft film state initially, and rain carrying dust can leave marks if it hits the surface. In winter when temperatures are lower, curing takes even longer; my neighbor's car developed water spot rings even after waiting five full days before rain exposure. It's safest to garage the car for the first three days as advised by professionals. If you must go out and encounter rain, drive slowly to minimize water splashing, then immediately wipe the car down with ceramic coating maintenance spray upon returning home. Avoid automatic car washes for a week after application, as high-pressure jets can damage the uncured coating.
