I bought the care package, 1 litre of the pre -and post wash, plus the chassis shield. Really good gear, I coated previous vehicles with fish oil, this is much neater / better. What I did was buy another 5 liters of the chassis shield plus a $12 pressure spray bottle from Bunnings with the 2' spray tube/Nosel. Works a treat, you can get underneath & point to those hard to get places spraying it under slight pressure to cover everywhere. Way to go ...!....;-)
