I need to do some painting on the car. And we can see that this place has been slightly deformed, but most of it does not need sheet metal treatment, mainly because there are some depressions in this position. It's best to do sheet metal processing or find a nondestructive repair, which saves trouble.
Mainly spray painting. At this level, if you use a touch-up pen or polish and wax, you still can't cover up the defects, and it is easy to corrode and rust under long-term exposure. At present, it is more convenient and economical to apply it with a complementary color pen first, so as to lay an oxygen-free seal for the paint damage here and avoid further deterioration.
