From their Website:
Excellent capillary action on initial application, which allows the product to penetrate the tightest of gaps.
After a few minutes the solvent evaporates leaving a highly adhesive, waterproof load bearing oil.
Splash-proof and saltwater proof. Also resistant against non-concentrated acids and alkalis.
Free from silicone, resin, and acid.

Evaproative base - seems good; doesn't attract crud = good, gets into tight places = good; -95F to +392 F = good; user says doesn't fling off = good.
Could this be better than the DuPont teflon dry spray?
