No, you should not try to do an entire car with this kit. It's just not designed for it. But I will say that for doing spot rust repair (quarter panels, roof rack mounting points, rocker panels) this thing is AMAZING!
Pair it with a good face shield and a decent respirator and I must say. This is the best $10 I've ever spent.
Wire wheels and flap discs have a horrible time actually removing the deep rust. They can take care of the brown crap on the outside, but if you don't get it to bright shiny metal the rust always comes right back. A spot that would have taken me hours to get to the point of shiny metal now takes me about 1 minute.
The only other tool I bought that was a better deal was my 1/4"x20tpi tap and handle I paid $3 for.
Anyway, that's my semi-rant about this thing. Here's a photo and a link
