I'm considering powdercoating my tub once I complete my welding/modifications but am still confused about the sequence of steps.
My thought to sequence are:
1. Make changes to body such as flares/drip rail deletion/stiffening mods.
2. Hammer and dolly to desired shape/fit
3. Strip entire tub by either blasting/dipping.
4. Powdercoat tub (normal coating or primer coating?)
5. Finishing body fillers/smoothing of worked areas.
6. Base color coat/clear coat.
Again thanks for sharing the wonderful work you guys do!

you basically nailed it. I am sure Keith will chime in with the details but the process is exactly the one you have outlined.
For the stripping of my car they used a baking procedure. Instead of blasting or dipping they baked the car at a very high temperature. This dissolved any possible residue of material attached to the tub (paint, glue, gunk etc).
The advantage over blasting and dipping was the fact that all the little spots could be reached without the risk of the acid getting trapped.
So from powder coating is basically downhill... it's just a question of putting it back together.
In my case we decided to swap to 930 trailing arms after the PC procedure.
So Keith had to move the pick up points for the TAs.
You can see the contrast with the rest of the car...
Since it was back there it was not a big deal (even though they were painted over in Mex Blue anyway).
Make sure that you get a close match for the color. I remember it was not the easiest task.
