Yep,eastwood has an undercoating system,comes with a 20" rigid and a 30"
flex wand ,I think I paid about $50..00 for it.

Works great to reach all the nooks on the underbody!

 LPS #3, Heavy Duty Rust Inhibitor is similar to the undercoating Texaco
sold, in the '60's.   It creeps; and is self healing.  It's kind of waxy
when it dries.  If you spay inside doors, make sure the window is up!
  I just used it on rear seat springs, after I blasted them.
  The 11 oz. aerosol has a snorkel tube.  These folks have it in a pump
bottle, or by the gallon, etc.

I had a '72 Ford as a dailey driver for a few years.  When I got it,
there were a couple of rust bubbles in the lower corner of the front
door.  I used my old trick of spraying the area periodically from the
back side, with motorcycle chain lube.  I like that stuff, because it
sprays in thin, penetrates, then the solvent evaporates.  Then it
leaves like a cosmolene grease to seal out the water and air.  The Ford
never got any worse for four years, when I sold it.  I have been using
this trick on my other cars now too.  Just don't get it near anything
plastic, like a lens, as the solvent will attack the plastic.  KK
