So the math looks something like "New car with white leather seats plus 3 kids under the age of ten == Leather Protectant in bulk". Is PBL recommended for white (Oyster) leather? The write up says it's "attractive on light colored interiors" but, then again, so does CQuartz Leather Coating right before it says "Avoid use on white colored leather". 
Obviously, there will be much spot testing done beforehand but what's the general consensus on it? If not, is there sealant that *is* safe for white leather?
