This is a tester!

My brand new Megane has been splashed over with what seems like cement slurry. Possibly this was thrown up from slurry on the road leaked from a building site. It must have happened driving at night. I didn't notice it until next day. The splashes are between half to one inch diameter and are the colour of oatmeal porridge. There are something like twenty to thirty splashes in all. They are on all panels and most windows. They are very hard with a gravelly feel. One on a window seal yields to scraping and it comes off as a powder. I tentatively tried Formula 1 Scratch Out. This would probably get them off but it would need prolonged rubbing with force and I can see it would damage the paint.

I need a genius now!

You might get a better idea than mine but if your car had a wax polish on before this happened the blotches will just be sticking to that, try gentle prising not rubbing with your finger nail, can you prise them off?

Or try a water jet.

Good luck with it.

A problem well stated is a problem half solved !

As Davesss suggested, I'd try a pressure washer using the water to prise them off.

best of luck.

i had a cutomer in who worked on a building site and had the same problem

i tried everthing to remove it, panel wipe thinners ,i tried picking it off and masking the sourounding area and using a plasic wedge to remove it but nothing shiffted it

it sets like cement when its on the car body work and in the end i ended up painting the panels as it was impossible to remove with out damaging the paint work

it may not be the same thing but from the way your describing it,it could be?????

they may be a way round paint work but unfortunatly i dont know the answer,may be some one could enlighten us

As cement has a high alkali content it may be worth trying gently dabbing the cement splashes with a mild solution of vinegar and water. Cement in itself has the ability to burn the surface of paint - so be gentle and dont force it
