the jack from my lincoln navigator works pretty well I'm going to jack up the back of the car and mix half the G2 paint. Then after that drys I'm going to use 2 jacks to jack up the front and paint the rest.
If you put the jack under the unibody jacking point, then how are you going to get the jackstand under the same point? Get a hydraulic and jack up the whole front or rear all at one time. The points to place that jack are shown in a diagram in the owners manual.
Come on why is he going to waste $40 on a jack when he'll probably never have to use it again. Here's what you do, get a large 2x4 with the jack that is in the trunk underneath the car. This way you have the jack in the center with the piece of wood lifting both sides. Let me know how everything goes.
