Look of bare metal??

[SS427]

Exactly as Charley stated. Boeing developed it for use on their landing gear that is subject to extremely high and low temperatures as well as liquid sprays. The nice part is, it dries to a dull finish and depending on how thick you put it on, you cannot feel it either. It is perfect for bare nuts, bolts, clips etc that people used to use clear on (which doesn't last). I have the link on my office computer which has been down for 2 weeks so look up under search words Boeing Boe-shield. It is available at most large marine or bicycle retail stores.
