We received feedback from customer in Dongguan on June 2025, the treatment agent turned white after spraying on rainy days.

　　Our salesman and engineer brought new formula at the first time, found that no white spots appear when used on sunny days, while followed up on rainy day, white spots came out.

　　After several times testing in sunny and rainy days, we overcame this difficulty and developed a new treatment agent that does not turn white when sprayed, customer purchase bulk order finally.
