Going to strip and paint my car, need advice and a recommendation for a book about it

When you take any car down to bare metal, you will find all the body work previously done, even a survivor taken down will many times show some filer used. All that filler work will have to be done again. The question is, IS that metal under the filler rust free and how well has that filler aged? Can you do that work or do you have to pay it all done?
The body shop that will take on one of these old cars don't work cheap, and they will tell you every time, IT must go down to bare metal OR they will not guarantee the work. $$$$$$$$$$$$$$$$$$$$$$$$
I have done more than a few that were great candidates to NOT take down. I have done some surviviors and finally got them down to the factory primer and that metal below the primer was great. That prime was one there!!! I epoxy primed it, fixed the dings and scratches, urethane primer, sealer , topcoat and just like in those TV car shows.... wa-laaa DONE (just like that!) and it last forever.
I see guys all the time buying a car think it has never been painted! just like it has only 30,000 mi.!
Point is know what you are working on.
Shooting single stage is like shooting anything. know what you are working with and what you are doing.
Yes metallic in single stage is lot harder to shot than that in base. People will have problems, trying to shoot anything piece by piece. You will always have changes in temp, humidity pressure, etc. Shot the whole car.
