Try this so spray does not go everywhere. Take a 32oz plastic travel cup (like from QT or somewhere). Cut off the cup holder part. Now you have a hollow applicator. Place the good rounded part (the part from which you drink) and place that on your stabilizer. Spray through the opening that you have just cut. It keep the spray contained and won't gum everything up.
Also, I like KK2000 better than 505. It doesn't seem like there is as much as the 505, but that little tiny can lasts longer than the much larger can of 505 and it is better for the environment.
