Will it remove coatings or wax?
Whilst iFoam Max is a strong product, a light application may not trouble a mature and well-applied high performance coating. However, it may weaken or remove waxes or sealants that are older, have been poorly applied, or that are simply less robust. So always assume you need to top up protection after. If worried about the power of iFoam Max, use our regular pH neutral snow foam (Apple iFoam) instead. This is actually designed to leave coatings unaffected and to work on delicate and sensitive finishes, although it won't have the ultimate cleaning power of iFoam Max.
Do I need a foam lance for this?
It works best with a dedicated lance, but it can also be used via a foam sprayer although the results may not be as good.
How long does the foam cling to vertical surfaces?
Moderate cling allows the dirt to be dragged from the car so it should not be a static blanket of foam; for much longer dwell use higher concentrations of product and apply in cooler shaded areas.
