Oh, I don't disagree, trust me with my mechanical background.
Dry is among the worst case, crappy lube is better than nothing.

While we strive to be in the "perfect world", Vaseline is way better than nothing.

Not everyone wants to spend "x" dollars on lube, just like some peeps try to do a season with one set of wing tapes to the fuselage.

I am not here to judge, just saying Vaseline is way better than nothing.

I have been chastised when pulling wing tape and balling it up.
I just "wasted" a seasons worth of tape....shame on me......
Thus I use Scotch type 33 white electrical tape. Not a killer on price and easy to get.
