Wonder if RustChek is like that stuff I used once. Some sort of a latex solution that bonded with iron oxide.
WD-40 Stands for Water Displacing 40. And is a decent rust preventative. Houghton Intl developed the first RPs in th e 1860's and still makes the industry standard for long term protection.
Every consumer test I have seen shows WD-40 outperforms everything else by a wide margin. Developed for use by the US Navy using your tax dollars so might as well take advantage of the investment.
I use WD-40 and it works really well i haven't used other things so i don't know what is a joke lolz...
I always prefer WD-40. Its quite useful!
I didn't vote in the Poll. I couldn't find Rustoleum in the list.
