Anti corrosion spray

[Halo]

What would you recommend to spray hard to reach parts of engine to stop it rusting?

make sure the surface is painted then wipe surface with a rag and any light oil at the start and end of every season.

I use Castrol Rustilo to give 12 months protection to agricultural equipment outside. It's a very 'sticky' oil and easy to apply.

Head and shoulders above any normal oil such as WD40, Duck oil, etc, for corrosion prevention.

ACF-50 is excellent - Good enough for the US Navy etc.

I've used it on motorbikes to stop corrosion setting in over winter etc.

+1 ..... and it's an aerosol spray which is what the OP asked for.

Brilliant - Have ordered ACF-50

Does ACF50 have any harmful effects on plastic and rubber?

Not on plastics or synthetic rubber but I guess it might on natural rubber, although I doubt whether much of that is used in engines these days.

WD-40 ? Did a Diesel engine course with an ex-navy mechanic who would spray the engine from top to toe in WD-40

Thanks.

ROCOL do a couple of rustproofers in aerosols.

ACF 50 had better be good, it appears to be about five times the price of WD40! £13 for a wee can? Am I looking in the wrong place?
I suppose it's a lot cheaper than a new engine, or even a respray...

It is expensive but very good, we use it on the Ducati's.

Same here!

My 1098R swingarm inner was swimming in the stuff after noticing how much water it collected.

I buy ACF 50 in 950ml bottles which come with a hand spray. Much cheaper than aerosols and does the same job without wasting money on propellant.
I get through a fair amount as it goes onto my classic car and tools as well as the boat.

ACF-50 is the go to substance. It is expensive but it works so long as you don't wipe if off with a degreaser or pressure washing.

There is a test online showing it's performance against scottoil 365 and WD40. Unfortunately the images are down

Thanks, that looks a better bet for using it on my saloon-mounted engine.
Just watched a video of someone doing a saltwate comparison test of no protection, WD40, and ACF-50. Prett convincing.

Is ACF50 also effective in preventing corrosion on aluminium alloys?

Any reason why it shouldn't?

WD40 is horrible. It builds up a sticky layer which eventually collects dirt and then starts conducting electricity. It is intended as a water dispersant (WD).
