Black Streaks Gone

Highdunno

I own a white caravan and have found a way to remove the black streaks which keep appearing after it has rained.                                                                              

Spray some WD40 on to a cloth and wipe them off,gone are the Black Streaks.

Dull caravan front from being left in the sun for a year before I bought it sprayed some WD40 on to a cloth rubbed it on to the front panels and brought the shine back(tried t cut and polish but didn't work).                      

WD40 also removes light scratches from your car believe or not.
