He is from the Adelaide office and was pretty helpful. He will sell you a small quantity or probably tell you where you can get it closer to home.

I use lanolin for all my rustproofing. However do it about 1 week before you hit the beach (or sand) as otherwise all the sand sticks.
However I haven't done the Disco yet. Mine has the standard engine/transfer case oil leak protection.

Ahh yes, next thing to fill out

a proper galve job is expensive yes but you can do a reasonable impression of it with cold galv in a can.

heat the area with a hot air gun after cleaning it back and roughing it up and then while its hot apply the cold galv I do this every time I weld mild steel with pretty good results.. and the cold galv also servs as a primer and if used heavily enough will also seal up a fuel tank.

The procedure used at Leyland Truck and Bus on NEW Series III that clients wanted treated against potential salt corrosion damage was designed by a specialist engineering consultant who stressed that if ferrous metals (and most others) were repeatedly or continuously used in a hostile environment such as a sodium chloride solution ( sea water) then corrosion is inevitable no matter what treatment or maintenance is provided.

The recommended procedure was:-

fill box sections with sufficient thinned mixture of a thinner and an active proprietorial preparation such as Tectyl, Rustlac, or Corroless to slosh around in the boxes, plug the holes in the boxes with plastic bungs, spray the whole underneath with tar epoxy paint, and then cover again with an active soft self-sealing anti-corrosive coating like the previous mentioned three. This will DELAY corrosion in a hostile environment if properly maintained.

Corrosion in ships commences, and is fought against, from launching to breaking. Don't kid yourself. If you repeatedly dip it in salt it will corrode. The stuff will get in the slightest fissures and work away.

Think will take ur advice and ye take drill/wirebrush attach to it all, then recoat in the most durable metal paint i can find.

With the fish oil, just apply b4 i hit the beach ye. WD40 or simmilar still do the trick?

haha just thinking fishoil + hands/clothes = unhappy gf for remainder of w.e

Make sure you wear Protective glasses, those wire wheels love spitting out spears and you can bet if you dont have goggles on one will end up in your eye, NASTY, Regards Frank.

Has anyone used or looked at the electronic CAT system? it's a little box that goes in the engine compartment and produces a negative charge throughout the vehicle which (supposedly) stops the chemical reaction that is rusting...

I got one "thrown in" when i purchased a new Prado... living near the beach and dunking the boat i figured it was worth a try... Haven't had any rust yet - three years later... but who knows if it's because of the CAT???
