more convenient than liquid. wished it sprayed in a fan pattern but I just spray it on then rub it in. the blue color helps you to see if you've got even coverage. very tacky and works well to trap dust and dirt.
Air box cover and exhaust plug fit well. I don't purposely wash the inside of the airbox with water but it does keep out the water that gets in there from the intakes under the seat when we are washing it. cleaner works very well.
