How does electronic rustproofing differ from spray-on rust prevention?
A. Spray on coatings only protect the particular area they cover, they are prone to being worn off and need to be maintained on a regular basis. ERPS covers the entire body of the vehicle including all the hidden and hard to reach places. The ERPS system has no wear components and other than occasionally checking the LED light, requires no maintenance. The ERPS system can also be transferred when updating your vehicle.
