Boeing T-9 spray lube - worth the cost?

[Josh]

My Dad is an avid cyclist and uses this for lots of things around the house and always swore it made his bicycle chains last forever so when I saw this at an RV store the other day I go to thinking. I wonder if it would be worth the price for use on RV's for various things. I usually use cheaper sprays like WD40 or PB's silicone spray or white lithium grease spray for things like hinges, locks, drawer slides, throttle linkage, etc..

I see Boeing now promotes it's use for RV's. Price of admission is pretty steep at almost $20/can. Maybe cheaper at non-rv stores?

Anyone have any idea if it's worth it or any experience with different products?
