Your professional advice required please.
My windscreen is always smeary in the rain.
Always has been and I suspect it might be that the shipping wax wasn't properly removed.
I should have moaned at the dealer I suppose but didn't and after six years it's too late.
I've tried allsorts, silicone remover, sugar soap, meths, vinegar etc.
I use Autoglyms Super Resin polish and Shampoo Conditioner.
I then use their Fast Glass or Glass Polish.
"Making progress" on a dark wet night is a pain.
Any product or process you can suggest?
