Can Bodywork and Painting Be Done on Rainy Days?

No, rainy days can have a certain impact on vehicle painting. Here is some information about vehicle painting: 1. Reason: Rainwater generally contains acidity, and acid rain can significantly damage the car paint, easily causing oxidation of the paint surface and loss of gloss. 2. Consequences: The humidity after rain can affect the drying speed of the newly painted surface, but the reduced dust in the air due to humidity is beneficial for painting. 3. Precautions: (1) If the car has just been painted, avoid contact with water and dust on the newly painted areas; (2) It's best not to drive the car out on rainy days, as the fresh paint is still delicate and can leave marks when exposed to rain, which may be difficult to remove even with polishing. It's advisable to park the car in a garage at night; (3) Sunlight is not a concern as it only speeds up the drying process of the paint, which is beneficial; (4) Avoid exposing the newly painted areas to chemicals and oil stains.

Honestly, doing bodywork and painting on rainy days is quite troublesome. As someone who's been repairing cars for over a decade, high humidity in the workshop is the biggest headache. Although the paint booth can be heated, the excessive air moisture during rainy seasons makes the paint surface particularly prone to 'pimples' (tiny bubbles) or whitening, looking like it's covered in a layer of fog. Moreover, after bodywork repairs, you need to apply putty, which must be completely dry before painting – drying time in rainy weather takes twice as long as usual. If you notice sanding marks or orange peel texture after polishing when taking delivery, nine times out of ten it's due to rushing the job. If you're in a hurry for repainting, I'd suggest doing the bodywork first and waiting for a sunny day to paint – the difference in finish quality and durability is huge.

Last week, the shop encountered a paint job failure due to rainy weather. The white SUV's side door showed color mismatch just three days after spraying, looking like a patch from afar. It turned out high humidity caused uneven curing of the clear coat. Professional paint booths now come with dehumidifiers, but during heavy rain, the equipment's dehumidification capacity still gets compromised. Metal panels are prone to hidden rust when exposed to humid air after sanding. The more practical issue—body repairs in rainy conditions require at least 48 hours' delay before painting, otherwise body filler may absorb moisture from inside out. Rush jobs never pay off in auto refinishing—perfect results demand ideal weather and conditions.

From a painting process perspective, the rainy season is indeed a high-risk period. Water-based paints are particularly sensitive to humidity - when relative humidity exceeds 80%, water vapor can become trapped on the paint film surface, causing reduced gloss or white spot formation. While solvent-based paints have better moisture resistance, they still require strict temperature and humidity control. Once when helping a friend with touch-up painting, I didn't check the weather forecast - it poured the day after spraying, resulting in dense fisheye craters in the clear coat. Welding areas during panel beating are also prone to moisture retention, which may lead to internal corrosion over time. Nowadays repair shops generally recommend avoiding construction during the East Asian rainy season.

Our boss lady dreads taking rush orders for sheet metal repairs and painting on rainy days. Although the workshop has a paint booth with temperature control, overcast weather brings two practical issues: Firstly, dust control becomes difficult, as rainwater carries three times more contaminants than sunny days. Secondly, vehicle pickup times must be extended—fresh paint requires 48 hours without water exposure, yet customers often drive 500 meters out of the shop and get soaked. We've seen too many rework cases: rain marks, bubbles, or even entire sections peeling off. Our sincere advice: for minor damage, temporarily cover it with touch-up paint and wait for consecutive sunny days to address it properly—saving both hassle and money.

As someone frequently handling insurance claims, here's a reminder: If paint issues occur within three months after rainy-day repairs, repair shops may blame weather conditions. Especially during concentrated hail damage repairs when shops rush, oversights are more likely. Some owners report spider-web cracks appearing half a year after painting - often caused by insufficient drying of body filler. While most modern car steel plates use zinc coating for rust prevention, metalwork grinding damages this layer, with rainy humidity accelerating oxidation. For proper repairs, choose dust-free workshops with constant-temperature dehumidification systems and insist on written warranty commitments.
