Menzerna Top Inspection Spray - 500ml One of the challenges of ensuring complete defect removal is the ability to inspect the surface for any areas requiring additional polishing. Since the polishing process itself can mask these remaining areas with compound residue it is necessary to completely clean the surface. Top Inspection was developed specifically for this purpose. Top Inspection contains no silicone, is completely safe for use in paint areas, body shops, and finessing areas. It is perfect for new car showrooms to eliminate fingerprints, dirt, dust and grime and will leave a perfect finish.
