Here is how the process works

The barrier protection of Noxudol never fully hardens and on a hot day can self-heal scratches and chips. Noxudol will never aid and abed corrosion by trapping salt and moisture between the barrier and what it is protecting, unlike any other. Not only will this protection prevent corrosion, it will stop it in its' tracks. Noxudol cavity protection creeps and penetrates deep into seems, which is crucial as half the corrosion issues originate on the inside of the vehicle cavities. 

The Hard wax for the underbody creates a tough, flexible barrier combined with superior corrosion fighting chemicals for superior protection. Noxudol with not damage seals, plastics, wiring, or rubbers, and actually works as a sealant/lubricant for window tracks and an insulator to electrical connections.
