Hello!
Just starting to get little bits sorted on my VTR, door pillars, windscreen wipers etc etc.... oh and the head gasket, radiator and tyres

I have one problem I'm not sure how to sort, never seen it before on VTRs, my last one certainly didn't have this problem, does anyone know what it is and how to sort it? Looks pretty crap and I want rid!
They look like tide marks of some kind to me....
BTW excuse the dust and dirt, it's off the road at the mo having head done etc, saturdays gonna be big clean and polish day
