Welcome to the Forum and to the Cub Family
There is lots of stuff - info, manuals, tips, tricks, and words of wisdom from some of the communities real pros, way too much to mention.
As is normal for me - I always mention this - read the Attention New Members and Guest sticky on this forum. It will provide a lot of information.
One thing I can address is the work load. I am in the process of restoring Jethro my second Cub. And you are right, there is a lot of work in doing a good job, starting with stripping away all the years of use/abuse dirt and crud. I enjoy my hobby and I do not want to get burned out and many others here agree with that point of view.
To that end, we are all trying to find ways to work quicker, smarter and with less pain and frustration.
Check out the link on the server Electrolysis or Rust Zappers. Then build a tank. I just took the front bolster out of the tank today - wow! talk about impressive.
After you have digested that info, let us know. There are a few different versions and some work better than others. Ask and I am sure you will get input on what type of tank to make.
Enjoy your Cub and its restoration, and again welcome to the Forum
