Strangely enough (I mean stranger than a thread about Vaseline w/o being based on sexual content)
My wife uses vaseline to keep her brush bristles greesed for a certain type of paint effect. She wraps them in Cling wrap to keep the vaseline from getting everywere.
There has been no noticeable breakdown of the cling wrap. The weird thing is that it now stays smooth, no wrinkles or anything. Not even the the ones that were originaly in the wrap. it looks like a thin plastic window with globs of jelly on it.
I take no responsability for damages caused by glad wraping a layer of vaseline to your motherboard.
