I have 2 different TREND routers and an assorted set of 8mm & 1/2" shank bits.
I have used TREND Rust Buster and always sprayed the bits with this after use - and occasionally on the telescopic parts of the routers. Finally the free sprays I had have run out ... is it worth buying the TREND product - or spray with WD40 (or something else)
if you live somewhere damp. Otherwise pointless.

Ah, when I saw the title included the words "routers" and "bits" I thought it was going to be a computer question :-) At least in the UK we distinguish in the pronunciation (if not spelling) of the computer and wood-working meaning of router; not so in the US where both are "rauters" with the first syllable rhyming with "cow".
There are better products than WD 40 for combatting rust corrosion. Boeshield T9 or Camelia Oil or keep them in a sealed box with rust prevention paper or motheballs
If in a sealed box use a camphor tablet or two
Waxoyl spray for car underbody protection should do the trick. £10 fr om Halfords.
or motorcycle chain grease spray from the same emporium.
What numpty would coat their bits in that?

For some years, I've been using boiled linseed oil under the car. I like to use it for internal woodwork, so I generally have a lot of it around, and I sort of imagine it helps prevent rust. No idea if it really does, though. It probably just makes the mud more solid :-) I use it as a sort of loctite, too.
In the days when cars were not undersealed as a matter of course, it was reckoned that Waxoyl worked best when several well-thinned coats were sprayed onto a thin layer of dry dirt - which soaks it up like blotting paper to form a felt-like waxy protective layer.
I'm not sure that I really need anything under there, TBH. I've a 2003 Fiesta, and underneath it still looks great. Loads of other rusty bits elsewhere, of course, but the actual body is good.
