This is was a Stage 1 Polish for David in St. Helens.
He called because his car bonnet was marked by bird droppings. I tried various processes, including pads & 3m green polish, in the end 1500 did the trick, the car  exterior was then completed with a 1 Stage Polish
I also cleaned the interior & dyed the boot carpet with satin black. A blessed touch!
David was delighted & left this fantastic review. Thank you David !
