1﹑Please stir well before use；
2﹑Please carry out pre treatment according to the actual needs, such as ultrasonic cleaning, phosphating, sand blasting, etc；
3﹑Please use the suitable strainer screen for filtration；
4﹑The coating should not be too thin and too thick, too thin to protect the film, it is easy to get bubble if it is too thick；
Warm reminder
Quality guarantee period: The expiration date is half a year with sealed。
