I've used Fluid Film for several years and it does help retard corrosion. However it can wash off and needs to be reapplied every year. (In fact I'll be doing that over the next few weeks for my winter use vehicles.)
I never heard of the product you described, but it sounds similar to Waxoyl.
My main concern (other than $) for the NH Oil Boss Wax is the fact that it dries onto the surface (though it is mixed with oil).
Wondering if this would accelerate rust.
It's mixed with oil, it won't rust. Oil is hydrophobic. As long as it's the right grade of oil (more like a tar which is semi-solid as opposed to liquid oil) it's fine. Just keep reapplying it regularly.
Sounds a lot like cosmoline to me. That is what I use, and I am near albany, ny in the mountains.
My car was basically rust free when I got here, and only the spots that have been hit hard by rocks or other debris still have the coating. I just clean off any light rust after winter and put some more on. Before winter I will hit the high spots with another coat just to make sure, but so far after two winters my 15 year old GX470 is doing great.
The military pack all kinds of stuff for long term storage, or traveling overseas. They used it in world war two to make sure vehicles and weapons would not rust going over seas.
It is great when you have a clean surface, the downside is it does not creep as easily as something like fluid film, so inside frames is a bit harder. However, once coated on the inside of a frame, I imagine it would stay there protecting the metal for a very long time.
Thank you. I will look into Cosmoline and Woolwax (I think Woolwax is the US version of Waxoyl).
