Why the brush weather seal garage door leave black marks on the bottom or top surfaces of the door?

As a professional manufacturer of brush weather seal garage door, AOQUN company is very clear about why there are black marks.

In order to save costs, some manufacturers use inferior black dyeing agent, and the coloring technique is poor, which results in brush weather seal garage door filaments quickly decoloring, and finally sticking to the door surface.

AOQUN can assure our customers that our company has always adhered to use imported high-quality color masterbatch, to ensure the effect of brush weather seal garage door dyeing, and never decolor. AOQUN’s brush weather seal garage door is different. Even after many times of frictions, there was no mark left at all.
