Road Tar on Ceramic-Coated Paint: A Careful Response
Identify tar-like deposits and use a surface-compatible removal process before deciding whether a coated panel needs further treatment.
Updated · NANOLAB Knowledge
Small dark deposits on lower panels may be road tar, but appearance alone is not a complete identification. Check the surface and coating history before applying a solvent or repeatedly rubbing the spots.
Clean ordinary dirt first
Wash the cool vehicle with the normal compatible process and inspect what remains. Separating loose road film from bonded deposits makes targeted treatment easier. Note whether the spots are on paint, PPF, vinyl or trim.
A cleaner suitable for one material may not be suitable for the others. Confirm the exact product’s compatibility with the surface and installed NANOLAB system.
Treat only as directed
Use the approved remover at the specified concentration and dwell. Keep it from drying and avoid uncontrolled contact with adjacent materials. Use a suitable discreet test where instructed.
Lift softened residue gently with clean media, then complete the required rinse or wash. Do not mix removal products or follow one immediately with another without an approved process.
Inspect after the residue is gone
Assess appearance and water behaviour after cleaning residue has been removed. A temporary change during solvent treatment does not, by itself, establish permanent coating failure. Equally, a persistent mark should not be covered with a topper before diagnosis.
Record the treatment in the maintenance log and review renewal versus maintenance. Contact NANOLAB when the correct cleaner or effect on the installed coating needs confirmation.
