A cure for winter drying of buds and shoots?

[Laserbeak]

It seems like no matter what you do, when it's cold and dry outside you can't keep your orchids completely safe from drafts of dry air. Small exposure doesn't seem to bother the adult tissues, but tender flower buds and new vegetative shoots can be damaged in a very short period of time.

After reading that mineral oil was safe for use on orchids for other uses such as pest control, I got the idea you could use it to kind of seal such things in a waterproof oil. I've tried it and so far, it's working great! No more dropped buds or shriveled shoots.

Maybe other people have been doing this for a long time, but I don't remember reading about it before.
