Ten years of tunnel washes
The problem. Dark paint that looked fine in the shade and terrible in sunlight — a full web of swirl marks from years of automatic washes, plus water spotting on the roof and bonnet.
What we did. Paint depth readings across every panel, a test section to find the least aggressive combination that worked, then a two-stage correction by hand-guided machine. Water spots were removed chemically before polishing rather than sanded.
The result. Reflections with clean edges instead of haze, and a sealant to keep it that way. The owner switched to a maintenance wash every six weeks and has not been back for correction since.
