Can a car be exposed to rain immediately after painting?

It is not advisable to expose a car to rain immediately after painting. The duration before the paint can withstand rain depends largely on the painting process and the type of paint used. Generally, conventional car paint requires about a week before the car can be washed or exposed to rain. However, with rapid repair technology, the paint can be washed or even polished just one hour after leaving the workshop. Once the paint is completely dry, it forms a hardened protective film on the surface. If the car is exposed to rain before the paint is fully dry, it can compromise the protective effect, potentially leading to cracking in the future. Additionally, exposing the paint to rain before it is fully dry can also affect its glossiness. Car painting involves applying a layer of paint to the car's surface to protect it, typically using baking paint. The car painting process includes steps like applying putty, sanding, dust removal, cleaning, masking, and painting. Materials used in car painting include standard paint, metallic paint, pearl paint, clear coat, and matte paint.
When we finish the work in the paint shop, I always remind car owners to avoid getting caught in the rain for at least 24 to 48 hours. The new paint needs sufficient time to cure, and impurities and humidity in rainwater can penetrate the uncured paint layer, leading to water spots, discoloration, or bubbling. I've encountered many careless owners who ended up with stubborn stains on their cars, requiring a full rework and adding hundreds of dollars in costs. I remember once before a heavy rain, we quickly covered a customer's vehicle with a car cover, successfully avoiding trouble. When the weather changes drastically, parking in the garage is the safest choice—don't rush out for a drive.
I made a mistake right after getting my car painted. Thinking a light rain wouldn't hurt, I let it get rained on a bit, only to find speckled spots on the side the next day. I rushed it back to the shop, and the technician said rainwater mixed with dust had damaged the paint job, costing me an extra 500 bucks in unnecessary repairs. Now I've wised up—after painting, I always park underground or cover the car with protective cloth, patiently waiting at least two full days to ensure the paint cures completely. Don't underestimate this step, or you'll ruin both the shine and durability of your fresh paint.
