This is a product used on cars to prevent rusting as well as provide lubrication. The description is very strong, "heavy duty", "wear resistant coating", etc. . I figured that it might make for a decent protectant on heavy use knives.
I coated an 18" Barteaux machete with Rust Check and left it 24 hours to dry. It didn't say to do this, I just was busy the next day. It comes out in a thick spray almost foam like and when it dries there are patches of gel left over - not for use on folders or presentation blades obviously.
I took the machete and did 250 cuts into grasses and weeds (about the heaviest were 1-2 cm thick stalks) to put some wear on the coating. I then mixed up a solution of 2 cups of water and 1 tsp of table salt and covered the blade with it and left it out on the step to drip dry. As a control I did the same thing with the 12" Barteaux which Rust Check was not used on.
After 1/2 and hour no rust on either blade. After 1 hour nothing again, and salt water again applied. After 2 hours salt water was once more applied. This time however some rusting was evident. The 18" machete had about 30 small 1-2mm spots, the 12" had large 2-4 mm spots (only a few) and about 4 5mm large patches. The coated blades looked to be a little better but not what I would describe as a success by any means.
At three hours both blades had large patches of black rust along the edge bevels and patches of orange rust along the flats. I again applied the salt water.
Eight hours later (the next morning), both blades were covered in about 25% orange rust and there was little clean steel visible. The rusting was different though. On the 12" machete it was mainly little specks about .5 mm in diameter and larger spots where water drops had dried. On the 18" machete is was mainly streaks the full length of the blade.
In short, after some light work, the Rust Check coating didn't seem to offer any protection at all. I think I'll try this again with Marine Tuf-Cloth.
