So Simple You Probably Never Thought Of It

This trick also works well for spraying insulating foam into otherwise inaccessible spots.

That would probably make your tubing a one-shot affair though wouldnt it? That stuff is sticky and nasty.

Not really, I used some 1/8" I.D. polyethylene tubing. If you squirt some acetone in the tube immediately after using it, the foam melts down. A small plug of acetone soaked paper toweling will push any residue out, After the foam has set up, it can be pushed out with a length of 1/16" rod. At any rate, the tubing is cheap enough and it allowed me to get into some pretty deep pockets so it would be well worth disposing of it after use.

Going through today's email, see "The Hobby-Machinist News", and see Bob (even through the horse collar PFD). What's up Bob? Good tip.

Great Idea! I never thought of making my own. (Being the bird doo head that I am sometimes...)

For my truck's rocker panels & other hidden salt trappers, I use something pre-made to shoot aerosol lanolin into the weep holes for rust prevention. The pre-made gizmo works on many aerosol cans, even paint. But your idea is a whole lot cheaper and customizable! I have had two of the ends of the pre-made ones fly off only to be lost forever inside the rocker cavity. The pre-made thing is http://www.kellsportproducts.com/fluidfilmwand.html

Your post inspired me to make your version and customize it a bit for my intended use. I took a 1" long piece of 0.250" brass round stock, turned 1/3 of the length down to fit inside the tubing tightly. I left some barbs on the 'stem' so it would not fly off inside the hidden component being sprayed, Next I drilled through almost exiting the other end. The final step was to cross drill around the 'nozzle' at 0.0625" for a 360 degree spray pattern. (Thus, blatantly & rudely stealing the pre-made one's nozzle design).

Thanks for posting the idea. I had fun making my version and spent zero dollars in the process. More importantly, I avoided raking the leaves, washing the car, putting up storm windows and such for a whole hour!
