Like other products, the paint market is mixed. Experts advise broad consumers, do not buy paint when greedy for cheap, must choose well-known brand products, so as to ensure the safe use of their own and their families. Don't be superstitious about the word "green" on the coatings package. Look carefully at the quality inspection report of the product and see if there is any rust and leakage at the joint of the barrel. Pay attention to whether the clear signs on the barrel are complete.
