So I have a MW coupe and yesterday after washing the dirt off on the bottom part by the splash gaurds I can still see yellow dots of where the dirt that I just washed off used to be. I tried srubbing and using more soap but nothing seems to work.. kinda sucks since the car has less then 150 miles..! any ideas on how I could get off what seems to be dirt stains on the paint?

 

Most likely have to clay bar it man. Use a Quick Detailer as a lube and clay the problem areas. Should get rid of it

 

I've had this problem with the plastic parts of every white car I've owned. I've never been able to get the stains out, but sometimes they fade on their own.

 

Rust spots (common on all colours, more so on white paint, in that they can be seen more easily. Remove with a detailer's clay process and a chemical paint cleaner

Environmental Contaminants

Acid rain, road salt, tree sap and airborne contaminants are very detrimental to a vehicles paint film surface. Brake dust or rail dust is very small, almost microscopic particles of steel, iron or their alloys. These particles carry a positive charge (due to friction) while the vehicles they land on are carrying a negative charge. The vehicle surface becomes a magnet, attracting and bonding the ferrous metal particles to the vehicle surface, mixed with moisture they oxidize (rust). Regardless of how clean you think your paint is there are still bonded contaminants on the paint that you need to remove.

 

agreed.... rust spots came off our Solstice with clay bar and detail spray.
