How to protect my car near shipyard tuas?

[baobao]

Hi.. Recently i had to park outside some shipyard to do some work..
but just today, i discovered my new latio was covered with sand dust. 
Came back home quickly "water" my latio to clear the sand..
lucky not much scratch after washing.
so how can i protect my car? i need to display parking coupon too..
Is car cover allowed at parking lots?

Yes, car cover is allowed in parking lot, same applied to motorbikes. But beware to be flipped open to check parking coupon without covering back.

i understand that some models of cover for motobikes can lock with normal padlock. Maybe u can check to see if covers for cars can be locked also coz i hear that these covers tend to be stolen from public carparks...
