my car kenah a few spots abt 5 cents/10 cents coin size spots of concrete splattered from a construction site.
initially, i thot cud get rid of it the next morning as it looked as it was gonna rain.
but next morning, after rain, i find that the concrete spots has hardened and when i tried to wipe off a spot, i ended up scratching my door side panel !!
anyone got experience removing such spots DIY ? ... now i also dun dare to wash my car for fear of scratching it more when washing the spots.
