Best to divide the project into digestible bits. Your DYI plan is a good one. Set up to put two wet coats of epoxy on the parts as soon as they are blasted or sanded.. Prevent rust and these are long term projects. One of the fellows here did a 38 olds coupe and it worked out well doing it that way. I know he did send out to have some of the small parts blasted..
I have tried most all of it and now do what is known to work..
