Not sure if this is the correct place to ask this question or if its been asked before.. but here it goes...

I'm trying to sand my car down myself to save on cost of paint..

Can anyone tell me if this is a simple enough job if i follow steps - to do on my own? And if so - could anyone explain to me what i will need to do this. What grit sand paper, a automatic sander - or just by hand? etc...

Any advice will help..

Thanks in advance,
