Spray-painting Trees?

The cheapest hair spray is the 'stickiest' and holds various color 'grass' the best.  John

Thanks for the feedback/suggestion rattler21! Going to give this a try today!

I have purchased bulk Heki evergreen trees and then I customize each one like this:  I spray each one with clear DullCote to provide the "sticky" and then sprinkle some "Burnt Grass" randomly on them.  I then do another spray of clear DullCote to seal the Burnt Grass on. I have done it to the larger trees that have clump foilage on the branches and they look a little boring. 

I have also made hedges doing the same thing but I sprinkle on a yellow or red to simulate flowers.  The hedges I cut from commercial stripping pads that go on those round floor buffers. You can cut them on a table saw or scissors if you don't have access to a saw.

So you should have no problem spraying your trees and then added the colored foilage to your liking and then a clear coat to seal it on.  Good luck.  JP

Here's a pic of a tree in the yard of the farm at the bend near the north portal of the White River bridge.  It was a solid, vibrant, Spring green when I bought it.  Some judicious application of yellow spray paint moved the calendar forward several months to mid-Fall.
