we use the wax to cover machines at work once they have been washed off and they will sit outside for a year or more till we next use them . i had an older outboard with some one had tried to repaint around the gearbox so i rubbed it all down to the bear metal and then waxed it. i then used it nfor a whole year before i got rounf to painting it and it was as good as new . i recommend it to anyoneHi I tried it on some salt encrusted and corroded rope guides on my boat. Made no difference. I think it might work if the items were soaked in it. I wire brushed all the parts to get them as clean as possible. Then put waxoyl on them. Not pretty but better than anything else I have tried to stop corrosian.
As an example of how good that stuff is. I do a bit of cycling. And keep a bike for summer and one for the nast salty winter roads. All the hubs/cranks and gears are treated with waxoyl on the winter one. I put a new back wheel on the winter bike and forgot to treat the anodised alloy hub. It is now useless and has turned into a greyish powder. Parts of it have just dissolved. The waxed parts are still all in good condition.
My engine is lathered in it too and the trailer. All the bolts and stuff below the waterline. I spray it clean with the hose when I get back home. The salt comes off, but the wax coating stays put.
