I use Fluid Film as a anti seize coating, spray in on bolts, under wheels and brake rotors, works perfectly. Got that tip of South Main Auto Repair LLC on YouTube. 

 

This guy does great impartial reviews.

You want something that is semi-fluid so it will flow into all the nooks and crannies.  You want it to stay semi-fluid as coatings that harden can trap moisture and cause more corrosion than no treatment at all.  As long as it meets those two requirements, it should be fine.

 

Heck we used to save used motor oil and inject that into cavities.  Made a heck of a mess but it sure worked well.  Possibly not the best choice these days though, what with environmental  regs, etc, etc.

The UK forum seem to use the Dinitrol

I wouldn't use used motor oil.  A friend of mine was buying old used handguns from China a few years ago and they were all badly pitted, I asked why and was told that the Chinese Government would just drop all the old outdated guns into 44 gallon drums full of used motor oil in the thought that the oil would protect them.  I have no idea how long the firearms were in the oil, decades i imagine.  The guns were really old Colts  among other manufactures from very early 1900's, apparently the used oil contains acidic contaminants from the combustion process and it attacked the metal parts of the firearms.

Just reminiscing, not recommending.

[Drakman]

It really opened my eyes i would have thought the oil was a good idea. 

[jbcollier]

Not used oil.  new oil would be a good, albeit messy, option.

[IamScotticus]

Messy, exactly. And stinky.

 

What makes these products worth it is an ability to tack to the metal and have enough creep to spread and cover bare areas over time.  And not stink.  It cannot stink if I can convince my wife to go for rides, it cannot smell. 🤢

Anything with lavender is ideal.

What kind of nozzle did you use?  The one from 3M looks like it has a bulb that is too big to squeeze into small holes.

I bought the 3M nozzles (Very expensive), but as you rightly pointed out, they were too big to squeeze in the rivet holes.  I ended up using the small tubes you get with WD-40,etc.. Not as long unfortunately, but it was enough to achieve my goals (You can see the difference in size in the picture). An option I considered was to drill a bigger access hole and then bung it up afterwards.
