Well Jim, seems like you always want an arguement. I only brought the paint stick up as a reference to some that think that dirt, fowlings etc. will not be attracted to the grease or oil. The example of the paint stick, grease on top, then oil film, then nothing, a little wind with dirt blowing around or a mouse, and see what is stuck to the stick. I'll bet the grease and the oil have particles in them, and the part with nothing has just that, nothing.
By the way the sticky mouse paper is not going to catch a mouse if there is nothing to "attract" him on to it.
