Answer: Good for you! That project will teach you patience, expose you to many like-minded people who love to share tips, and selling your finished car may make you a few thousands dollars or more - when you sell it.
Rusty cars are the worst to fix, and the most expensive. Welding will be needed early on, along with body finishing, painting, upholstery - and of course, engine and transmission rebuilds. Complete one section at a time - you may have several sections in progress - but finishing one section shows good progress and always inspires me onward.
Some do the body work first - some, the engine and transmission, brakes, so its drivable, first.
Cleaning and then painting the - what you don't see part, may mean the transmission, engine, and interior needs to come out. Redo that paint like original - customizing what shows is the owners fancy, if you go there.
Hot rod magazines at the grocery store have good stories and pictures about such project cars to help you along. Will we see your car at Barrets car auctions going for $150,000? You never know until you try.
