Fish Oil

[SiR_RB]

Herd afew people recommend using fish oil, or the more modern form of spray which is called cavity wax, to there cars to prevent corrosion and rust

Exactly where do you apply it ? Inside the doors ? Boot ? Anywhere else ?

Is it worth doing or not worth the effort ?

It's not worth the effort. Basically you would have to coat everywhere rust is susceptible to start.

If you have rust then treat it and paint it. Keep a watchful eye and paint any exposed metal

Mainly used in areas with snow and salt on roads (US, UK, Europe, etc). Kinda pointless in Oz. Here main issue is blocked drainage, neglect and poor repairs

Fish oil is a blast from the past.

Used to stink dreadfully and when the car sat in the sun, the oil would drip from every orifice leaving a lovely mess.

You'd get it on your clothes, it would blow on the windscreen forming an impossible to shift smudge.

Cats liked the car though.

Try Tectyl these days, apply with spray gun and applicator nozzle/hose for those sealed areas.

Lol I remember those days. One g/f refused to be picked up again after I used some on my chemist delivery Escort.

It also blocked drainage holes in the bottom of the doors.

Do you already have spots of surface rust?

Wow thanks for replies guys lol

No rust was just seeing if it was worth doing as preventative maintance

That's great one less thing to do

The answer to your question is yes it is worth while. Thin enough to get in between all your seals and seams and the stuff sold today doesn't smell. Spray it in you engine bay, chassis, door frames then wait 2 hours and look for drips to clean up. It cures to a flexible barrier. Reapply it every year or 2. Where there is oil there is no rust. That's why hotrodders and people that to classic restos use it all the time. They use engine oil too... ha ha. sometimes the old way is the best because it's proven to work and fish oil has been doing its job since the early 1900s to present day to prevent rust on ships.

Hmm, I still had some that's from the 90s - not so thick - not so smelly - just right according to 'Goldilocks' I presume.

My can has never been used for car metal protection - although I'd think about it if I was living near salty air.

It still comes out of the atomiser after all these years.

Ha ha. Always used it since an old school panel beater that fixed my HJ back in 86 who had all these old valiants, I said to him about the rust problems they have and he said to me in broken English, ' where there is oil there is never any rust, fish oil everything' ha ha. He used to paint the chassis in engine oil and fish oil everything else. I have done it myself ever since with great success.
