You can learn to paste car clothes in about 2 weeks (15 days) if you have a foundation, and in about 2 months (45 days) if you don't have a foundation.
Training institutions need to pay for study. The tuition fee ranges from 3,000 to 5,000 yuan, and the teaching experience is about 1 month. After learning, I basically got a "driver's license", knew the theoretical basis of the technology and skills of sticking car clothes, and finally practiced in the society, and almost got on the road.
