central blast cleaning sent me an email today,
they spray the underneath, the interior and the engine bay, but not the panels, they DA the panels so they wont have any paint on them but dont blast them as it would distort the panels.

they quoted £1,300 +VAT for this on a renault 5 convertable, that is probably 1/2 the size of an escort and a lot easier as it has no roof.
that is if i totally strip the car to.
