"With this application, the white areas tend to green-up just enough to prevent most sunburn."

Just a small footnote to what I have often read from other members or heard from some plant hobbyists concerning variegation;
fertilizers, amount of light,etc., (and including any other EXTERNAL factors that might seem to affect variegation) DO NOT affect mutations (the white or otherwise variegated portions of the leaves) in a plant. This is a myth and I have often heard that "you can fertilize the variegation right out of a plant". This simply isnt true. The portions of the leaves exhibiting the absence of chlorophyll remain whether the plant is fertilized or not.
It is true that the amount of light can affect the brightness (or dullness) of some types of variegation in plants, but the areas which lack the chlorophyll is still present and does not change. The mutation causing 'variegation' is a lack of chlorophyll in these areas of the leaves- so it can not get more green, or less green, in the portions of the leaf where the LACK of chlorophyll is present. Fertilizing variegated plants, such as bananas, will of course make for a stronger healthier plant. With a sturdy well fed plant like this, it is more capable of supporting the areas which are non functioning (the variegated areas which have no chlorophyll) and then these areas would be less likely to brown out, at least in the instances where it is caused from not being fed enough by the remaining green functioning areas of the plant.
