I came across this product when I worked in the Cairns region. It was by far better than any other penetrant available.

The article was lifted from another US publication... hence the odd names...

We'd all like to hear feedback on how well these homebrews work.

Apparantly vegetable oil can work equally well when mixed with acetone.

A fisherman mate of mine had a lobster boat shipped up to Brisbane, with the intention of turning it into a crabbing boat for the Bay. Needed work, I volunteered to work on the engine , a Perkins. Fair amount of rust, not wanting to create more work than necessary, we discussed how to approach the job. He produced a product that worked better than penetrene, or any other product I'd used - Ti Tree oil. Amazed me, Bob

bolt-off,--the tail I was told---little old lady with the home brew.

magic stuff used it to get alloy a/c hoses apart.

I used my home brew of ATF and Acetone on the exhaust manifold off the 300TDi the other week.
I had to dismantle the manifold out of my old Turbo, one side almost fell out, but the other was stuck fast, some vigorous banging with a brass drift failed, WD-40 was next to useless as always the last 1/8th of the contents refused to come out of the can, Oxy torch and more banging wouldn't budge it.
So went searching for my spray bottle of ATF/Acetone, sprayed it liberally around outside of joint and waited an hour. Checked inside manifold and you could see the stuff had worked its way through (about an inch and a bit).
Anyway while carrying turbo and stuck manifold log over to the vice the manifold log fell out, good ****, Regards Frank.

just a regular spray bottle? I want to try some but wasn't sure if the acetone would affect the plastic or seals or whatever

Will be trying the home brew mix as well - nice and easy and cheap.

Try here...

PENETRENE BULK

Bought a litre of "Diggers" acetone recently and the bottle appears to be made from polythene. I wouldn't normally spray the stuff in any event. I mix a small amount of the brew enough for the job in a tin can and use an appropriate size paint brush...
