I have seen another carbag made with VPI in it. Is that good?
Well, yes and no. VPI or VPCI stands for Vapor Phase Corrosion Inhibitor. VPCI’s work very well at protecting metal from corrosion, especially in critical areas. However, it will not prevent mold and mildew. Nor do we have data to confirm how it reacts with all materials in a vehicle. Also, VPCI vaporizes readily and will “leach from the material over time. Then all that remains is a plastic bag.
