Stripping paint and prepping car for paint

I am going to start on the body work for my Scamp. It's pretty much a complete resto. I was wondering about paint stripper? I have heard a lot about aircraft stripper, any one have any experience with this stuff? How much do I need for the whole car? Is it easy?(dumb question, nothing ever is)also once stripped, do I need to sand and prime right away? Any help will be greatly appreciated! This will be a first for me. I plan on doing all the prep my self including replacing/patching panels as well.
