Something else sheep are good for

I'm quite keen on New Zealand-made Prolan as a corrosion inhibitor for the Jeep's chassis. It's made from wool grease and you'll find an earlier report here. The Tauranga based company has now developed a new product, Prolan Enduro, for under-chassis corrosion protection. It dries to a shiny finish and is said to be very durable. I've sprayed my chassis and will report back later. The fancy looking red and white nozzle is also new and seems to work just like the old one! I had a leaking problem with the old nozzle, so this might be the fix. By the way, those of us who use the lanolin product are in good company, the cranes and barges trying to get containers off the Rena are coated in the stuff. Here's Prolan's home page.

Not a sheep joke

I've been spraying the underneath of the Wrangler with a sheep byproduct that I'm hoping will help keep rust away. Lanolin is a good rust preventive, as many farmers already know. Lanolin is a greasy, waxy substance taken from sheep wool after shearing. In Tauranga, ProLan NZ manufactures a range of lanolin lubricants, corrosion inhibitors and anti-seizes and it was to this helpful company that I went for my $84 four-litre can of liquid lanolin, plus a spray applicator. Mostly, ProLan can be wiped on, but the spray is good for reaching difficult spots. I've done the entire chassis and the ARB bumpers a couple of times now, and still have heaps left in the container. The waxy residue certainly feels like it will do the job, but only time will tell. 

Update: Six months on, the trigger mechanism of the sprayer started leaking badly, wasting a lot of the product. I emailed ProLan to ask if this was to be expected. Apparently it isn't and they had a new unit and spare trigger mechanism on its way by courier next morning, at no cost. Great customer service, guys!
