There is definitely no phenomenon of bubbles in the paint of a new car. Bubbles in car paint are only possible after the car has undergone innovative repainting. There are many reasons for blistering, and the most likely reason is the influence of moisture.

The first type is that after the car is painted, water is inside the paint film. When it encounters heat, it needs to evaporate, which will cause pressure to bulge on the surface of the car paint, causing bubbles. When it is cold, that is to say, when the temperature is not so high, the bubbles disappear. In fact, it is the same principle as heat expansion and cold contraction. Therefore, when the car paint is painted, each paint film must be dry and thoroughly dry, and it is not allowed to leave water. Most of the reasons for this situation are due to improper paint operations, such as the inability to dry after water grinding, the use of gasoline instead of oil remover for substrate degreasing, and incorrect paint ratio!

The second condition is that the quality of the car paint material is unqualified, because when it is rainy and humid, water vapor can easily invade the inside of the paint. When the temperature rises, the outer paint film seals the water vapor inside, and after the water vapor evaporates, it cannot come out, causing the paint surface to bulge and blister. So the quality of car paint must be up to standard. If car paint needs to be painted, it is necessary to choose a large, legitimate car paint factory or 4S store. We have always advised all car owners that cheap goods are not good, good goods are not cheap. If you want good quality, don't worry about prices!
