Sorry, got a bit "button happy" there and only just realised. Quite right Jagannath, I had a bottle of AK Ultra come through the post yesterday and sure enough there were the opaque patches. I'll have to save it for vehicles that need an extreme flat finish. Then tomorrow it's off to the shops for a Windsor and Newton Galleria and try again. Back to the drawing board as they say!
Many thanks again to one and all for your input and rest assured I'll keep you posted.
Cheers
