I am cleaning up a jointer that I picked up on Craigslist a few weeks ago. The dovetailed ways were a bit gunked up. Before I reassemble, what kind of grease should I put in the ways? I don’t want something that will collect all of the dust and chips.
Thanks,
Alex

The spray can, or the bicycle version?

I tried using a bow shield once, but had to cut a fole for the arrow to go through. ;-)
Just to add to what has already been presented
I don't recommend T-9 for bicycles; builds up too much. Simpler is often better. Ten weight machine oil on the bike chain; very little of that. Just enough to freshen the factory lubricant. DO NOT wash out the factory lube with solvent to put in some of the over priced stuff designed to make the manufactures money. I work with this stuff on a daily basis.
So. . . since it is not best for that perhaps you may want to at least explore this . . .
There is such a thing as "Way Oil". Go to a machinist supply and buy a gallon of it (they may not have a smaller quantity but if you have other machines . . . ). It can be super cheep that way. A few dollars for a gallon.
The ways on your jointer move so little and over such a short distance it probably does not matter in the least.
Thanks for the input everybody. I will try to find the Boeshield spray.
No way I need a gallon of way oil! That would be way over the top.
Ain't she beautiful?

Yes ! Quite Nice
Good find. I hope it works well for you.
"Way oil" is intended to be
"Way oil" is intended to be used in sliding mechanisms in metal working machinery which are continuously in motion while the machine is in operation, like the carriage or cross saddle of an engine lathe. It has less additives than "gear oil" since the large bearing areas typical in sliding mechanisms do not subject the oil film to the severe shear stresses associated with shock loads on small bearing areas in gear trains. Both are different than "spindle oil" which is intended for high precision, high speed ball bearings.
If you look at a mechanism that uses way oil or gear oil or spindle oil, you will see that there is a provision for continually renewing the oil--some kind of oil pump.
When you take a machine apart and have one chance to get lubrication into it before you put it back together, you mainly want a lubricant that is going to stick around. You don't need a lubricant designed for shock loads or high speed motion or continuous motion.
Apply lithium grease sparingly before re-assembly, and the next guy who takes the machine apart years from now or decades from now will still get it all over his fingers.
