"It's kind of like "Stick-em" that goop NFL wide receivers used in the 70's..which was banned..."
I had this mental image of a golf ball sticking to the club, the player looking down the fairway and saying "Wow - I hit that one out of sight!"
But I would think that it needs to lessen impact of contact (i.e. slippery) rather than increasing the effect (i.e. sticky). And if you remember football back in the '70's you'd see guys just covered in that stuff - especially late in the game after it had smeared around a bunch. Always wondered how the players got it all off after the game. I think, besides the rule change, that the advent of thin neoprene gloves was a factor in its discontinuance - get the grip without the mess.
If you've been around the game long enough you've seen plenty of illegal products advertised in "reputable" golf sources. Though many of them would have the decency to print "Not legal for official play" or something like that in 1 point font at the bottom of the page.
