It is a process is usually a dense cladding (often based on rubber) applied completely to the undercarriage of automobile's. It is normally sprayed or painted that provides long term protection from corrosion of automobile's parts like frame rails, transmission parts, exhaust parts and internal body parts. Then also a thick coating reduce wear and tear and absorbs noise, Avoid dents and scratches due to loose gravel roads and off roads.
