Be a bit carefull what you do. I don't know about laquer but I do know that the mating surfaces between the wheel & hub and the bolt heads & wheel must be clean and free of paint. Failure to keep these surfaces free will affect the tourque of the wheels and may lead to wheel loss. This is a well established fact, at least on truck wheels, and I don't see why cavavan wheels should be any different. Halford's "boy racers" are exactly that, they are not trained technical advisors.
