I always buy a bottle of Sanhe automatic spray paint online, clean it, separate the periphery with newspaper, then stick the newspaper 40CM away and spray it. If it is deep, spray it several times1one bottle of 0 yuan, and pay the courier fee of 5 yuan. You can buy metallic paint and fluorescent paint for one year, but you don't need a bottle of paint. If there are too many cars, paint the whole car 300-500 yuan.
