Updated · NANOLAB Knowledge
Practical approach
Identify approved surfaces and follow the engine manufacturer's care instructions alongside the coating guidance.
A clear-coated painted area may permit a different preparation from an adjacent decal or textured vent.
Decision limits
Do not coat controls, ventilation openings or functional parts outside the approved cosmetic scope.
