Clay bar and plenty of water.

Brasso.

The house next door was rented out for some 20+ years. About 19 years ago the lunatic bought a wreck of a caravan to be pulled by his wreck of a Pajero (fitting description of him!)

He decided to spray the pull bar of the caravan with tins of aluminium spray paint.

I was out, it was a windy day & my 2/3 year old Xedos was covered by spray on the bonnet, front wing & driver's door. Bigger bits were removed by my thumb nail, the rest was removed with methylated spirits & paint restorer by Autoglym & gently rubbing with a fine cloth - about 2 hours work. The car was washed with lots of soapy water - applied Mer- it rubbed up perfectly.

The neighbour denied it was anything to do with him. A few years later his Father-in-law's rotting MB was next for his spraying skills on a windy day - I marched out & told him he would be responsible for any paint mist on my cars & it would be professionally valeted at his expense even if this meant Small Claims Court! He backed down & went elsewhere.

>>Mer! Not heard that name in years!

I did say the incidents were in the past.

That said, my neighbour, who washes his car at least 2 x per week still uses MER. Polishes his car about 6-8 times per year, hoovers 1 x per week.

He must have bought the warehouse clearance.
