[TowerTalk] WD-40

[Patrick Greenlee]

Eddie, Thanks for the splendid idea!

I sometimes use a small diameter length of plastic tubing or a small 
diameter soda straw as a pipette to put a few drops where I want them.  
Harbor Freight used to sell (and may still) DIY metal reusable aerosol 
bottles made of metal. They have a Schrader valve to pressurize them 
from shop air or bicycle pump and are pretty solvent proof.
