Under body Oil spray

Where from can I get this lanolin? I'm tipping I can't just pinch the stuff the missus rubs on her legs...

You can get it from Bunnings and just about any hardware store. Made by Lanotec (may be other people also).

This stuff can be sprayed and is about $21/litre. I use to lubricate stuff, rust prevention, loosen nuts etc. Very handy stuff.

If you want to make heaps of it cheaper you can get two containers of Lanolin grease (500ml each?) and then scoop them into a 20L drum of WD-40. Then shake thebleepout of it for a while (my Dad leaves it in the back of his ute for a while). Once dissolved into the mixture it doesn't settle at all.

A word of advice though is to spray it on very thin. Otherwise it will run off onto the floor. Lots of thin coats is the way to go. Wipe over it all with a rag too so it spreads out nicely.

Thanks Utemad, seen it mentioned in a few threads, but really didn't know what I was looking for... The trade name should help.

I have seen the 5 litre containers at the hardware also. They are about the same cost as you stated.

I should get one next time but I have only bought 3 litres in about 3 1/2 years.

I agree totally. I only commented on the rust proofing side of things. I did say however that I have a complete chemical rust proofing also. That includes the bitumen looking black stuff underneath. Some clear coat stuff in the engine bay and that sticky crap inside all the doors and nooks and crannies in the bodywork.

However the lanolin is great for touch ups. I use it underneath to protect the mechanical components like the brake backing plates and whatever else I can find. When I hose underneath the water instantly runs off as there is so much lanolin under there. Like water off a ducks (sheeps? )back.

However none of this will protect you if you don't give your vehicle a thorough wash when you get home. I have one of those staun angled hose attachments and it is great for getting the sand out from where you can't even see. I also wash the car twice. Once when I get home and again about a week later just to make sure. Doing it thoroughly like this also means you are constantly looking and will find rust earlier than if you didn't. Sounds like a lot of work but I don't have any rust :-)
