Wow what a request and subject
It would take a book to cover all the possibilities
As in the past I think my normal guidance/suggestions go as follows
1- Truefully evaluate your abilities to complete the job - both in time and money. IF you have already figured what the project will cost - consider doubling it.
2- Evaluate if you have the room to work on the car and store all the parts once the car is disassembled. It will take three times as much space apart as together so make plans and plan ahead. Painted hood and fender may need to be stored in a well protected area - time to make sure your significant other understand the impact this project might have on the family. Slept is a number of friends homes in the spare bedroom next to painted hoods and fenders over the years. Not uncommon for some to have nice fresh parts on the pool table in the family room or boxes of parts on the formal dinning table. Doesn't work too well in my home
Is the work area secure from little children? Not a great idea having them around cars, chemicals and allot of parts during the process especially when your not around.
3- During the evaluation figure out what you can do yourself and what has to be sent out. Start interviewing and getting to know those services and people - while finding back up if things change or fall through.
4- Do you have the tools to do all the jobs? Goes hand in hand with the idea of farming out some of the processes.
5- Take tons of picture - three or four of everything from all angles. Its a pain and tiring but it will pay off long term even if the detail is not 100% correct.
Even though you will think you'll never need a picture - you will guaranteed.
6- I normally start a binder, a sub file in my computer and a list (I use Publisher but Word or something similar will work) that I continue to up date through the project with detail pictures, notes, things I need, things I need to order, things I need to check on and so on.
As I figure those things out those items are not deleted just moved to another section, because I WILL need that info sometime in the future for something. From there I simply print out the first or first two pages everything I go to work on the car adding those pages to the front of the binder.
6- Buy allot of cheap sealable Baggies. Big ones and small ones and a marker and use them. You'll still always be shuffling throughout bags looking for stuff but it beats digging through cans and buckets of parts looking for matching bolts
And raid the recyclable bins behind stores for a bunch of boxes - different size and shapes, Knock them down so that they store easier but have them handy.
7- I also buy and use plastic wrap - either the store stuff or the commercial stuff to wrap painted or plated parts while they wait to be installed. I often try to redo the small parts and sub assemblies while the car is being painted and or the body work is being done. Makes it real nice to have something all ready to take off the shelf that is ready to be installed right away.
Think that is enough for now - sure I missed allot and other will add it.
