Re: Rust | Very Scared
I would be hesitant to use WD-40 for anything but very
short-term protection. And, don't put it anywhere that won't
be wiped and re-coated regularly, such as: on shafts, linkages,
ways, bearing surfaces, etc. It tends to polymerize if left for
extended periods, becoming gummy and difficult to remove,.
I once created a real mess for myself by using WD-40 on
a transit (surveying instrument). After it sat for a few months,
it took me several days to clean the stuff up. Now, if you have
moisture somewhere you don't want it - use the WD-40, WD
stands for Water Displacement. Then, lubricate with the proper
The light machine oil solution is your best bet for short-term
protection - perhaps up to a couple of weeks.
For severe conditions, I would look to the firearms aficionados.
They are very serious about keeping metal from rusting. One
of their favorite products for short-term protection is "BreakFree
CLP." For long-term and storage situations, many tend to favor
"Birchwood Casey Sheath."
Having spent many years in machine shops, I feel that oil and
lots of it (within reason) is your best friend. I always keep an
oily rag around for wiping machine beds and ways.
BUT REMEMBER: Guard against spontaneous combustion as
if your life depends on it.
