Earlier this year i took my 2001 Nogi blue S3 off the road while i build and fitted,
The problem now is that on the bonnet and rear of the roof when under the tell tail lights of a petrol station or on a sunny day there looks to be water marks that will not come off, Ive tried the normal clay,dodo juice lime prime, Autoglym super resin pollish and wax but no matter how hard i work it they will not move,
Out of frustration i asked a lad i know who works as a painter at BMW to run a buff over it with some "lite compound" it looked better but when i pulled it into my workshop... they are still there !
The bonnet has been painted when i first got the car about 3 year ago but i know the roof has not,
Any surgestions please?
