Allen Jones of Verridale QLD, inquired about placing Knockout Rust® on the springs of his boat trailer, as it needs to be submerged when launching his boat. My answer was the rule of thumb is, although KO-66 has a wax seal, you never place a lubricant type product on leaf springs, as it can attract dust & grit. Allen contacted me some months later advising he had ignored my advice, saying he had coated the springs, axels and weld-joints with KO-66, now when he takes the trailer from the salt water, the water beads off immediately and the wax skin has set, collecting no dust.

Terry Nicholas of Terry's Rust Panel & Paint Palmerston NT explains...
Because of rotted vegetation over the millennium in the swamps of the Northern Territory, these swamps now contain a degree of sulphuric-acid. This acid plays hell with local vehicles used for fishing & sport, especially 4x4s that are used and abused in this part of the world. On receiving the initial shipment of KO-66 rustproofing from you I carried out some tests of my own on the product. They consisted of applying KO-66 on different pieces of steel and then for 24 hours I placed - One in sulphuric acid, One in Water seven times saltier than the sea; and another in a potent vinegar mixture. To date 27/9/04 I have never known a product to stand up to these tests as has KO-66. while the salty water and vinegar tests has the metal around the mixture in a very rusty condition, the exposed metal from the sulphuric acid test is now almost eaten away, except where the KO-66 is spread. Here the metal and product are in their original condition.

Because we live at the beach near Sarina in North Queensland, the salt air in the off sea winds is a real headache. We have found this tar based product to be a real saviour in preventing rust in our vehicles. After coating under the mudguards of one car we drove on a dusty road before allowing the required drying time. This proved to be a good mistake as the wet tar picked up the dust. We then sprayed on another coating giving the car a great sound proofing as well as the desired rust proofing.

Recently I visited my parents' dairy property on the coast near Warranambool in Victoria. Using KO-66 on some of my father's farm machinery, the family were delighted with the results and are now using it on just about everything on the farm that has exposed metal
