Drawbacks:

• The curing of the coating takes several hours or even days, depending on the type and thickness of the coating.
• The coating should be re-applied after different intervals of time as the underbody is constantly subjected to floor impacts.
• The coating should be inspected periodically for damage and wear and must be repaired quickly if found any so that it can retain its value.
