[Shop-talk] Painting inside a chassis

[malaboge at aol.com]

Fellow rustaholics-

Once you clean the inside of the frame a bit, you might try this option.  I
used a few of the longest Bundyflex brake lines (avail at your flaps) and a
small sprinkler head (about a 1/4" in diameter) from an irrigation system.
They're plastic and available in a 360 degree spray pattern.  Use your Weber
jet drill (Holley also acceptable as well...or for that matter any smallish
drill bit lying in the bottom of the drawer) and enlarge the spray holes a bit
to allow the somewhat thicker medium.  Superglue your modified spray head to
the end of the Bundyflex.  To "propel" your mixture I used a new lever style
grease gun, with appropriate fittings to mate with the Bundyflex.
Drill a hole in the end of the frame at each end, stick the bundyflex in half
way, fill the grease gun, pump the lever and pull the whole magilla out as you
pump.  Once you've pumped enough POR or Rust Mort or whatever you're using in
the frame, rotate it on the spit as it dries so as not to pool all in one
spot.
Worked well for me and using a borescope later, I could see that it really did
coat well.

Yeah I've gotta get out more...
