The other say I painted our porch. Before painting it, I sanded the old white paint off with an electric sander. Stupidly, the cars (both black) were parked on the drive nearby.

(Can you see where this is going? )

By the time I was finished, it was quite late, I was knackered and the cars were covered in white dust. To avoid the dust sticking to the car with over night dew, I just hosed both cars down and walked away.

(Ok, we are almost there )

The next day, the water had pooled (well polished you see ) and evapourated to leave the car covered in watermarks (basically calcified rings in the shape of golfball sized blobs of water). I didn't panic as I thought that a Zaino session (clay, wash, polish, top coat polish, detail spray) would solve it, and besides, the cars were both overdue some attention.

BUT... two hours later and the watermarks are still there

What do I do? Anyone got any experience as to how the paintwork stands up to a soaking in Cillit Bang or LimeLite ?

 

Vinegar should remove them, but will also remove all your Zaino. Sounds like the paint from the sanding may have dissolved into the rain water.....

 

white vinegar will do the job but strip everything else too
