Is that the discontinued product? I still have about half a can. I've had it for decades and never considered this use for it.
DL, yep, discontinued, but of all the waxes I have, it was the "softest". I have learned that mineral spirits are used as part of the mix (for most any paste waxes) and will re-soften them up so my crunchy can of Minwhacks probably could have been used.
I also like "Waxilit" for joints, but it is a white wax that can be difficult to remove from the wood grain afterwards.
