want to ask u guys....why my brake got something like orange spots ...is it karat or wat

u guys don't have problem driving persona in rain? i got problem with the side mirror....it seems if the rain is heavy, the rain is blocking the side mirror...is there any accessories that can avoid the rain from blocking the side mirror?

yup...i mean the water drops...but my problem is when i'm driving during the rain, the rain drops will hit the side mirror (i mean the side mirror kene tempias hujan)....then, it will block the view of the side mirror during the driving....so is there any accessories that i can attach to the side mirror so that it can block the rain drops...sumting like a visor or sumting....
