not a bad idea its one of those sonic ones .... not sure what concentration im using the biberry as i didnt write ont he bottle and forgot. i think its about 5:1 or whatever it said on the bottle to use.
i did find that it was way to easy to put too much on and just watch it dribble down the drive after running off the wheel.
