It really depends on which process you go with - not all dippers are the same. I’d avoid the ones that strip with acid, especially if they use hydrochloric acid. That’s the worst offender for getting trapped and not properly neutralised.
I used Enviro-Strip in Tamworth. They use phosphoric acid in one of the dip stages, which is less problematic, but the actual paint stripping is done through pyrolysis - slow bake to 400 degrees in a large oven. That turns everything to ash. The dips wash the residue off, neutralise any rust, and zinc phosphate the shell. Guess I will find out how it works long-term; my only criticisms have been that here and there, in certain tight spots, the ash residue of things like seam sealer have not been completely removed, needing to be manually dealt with. Also, I’ve had a couple of spots where some dip fluid has shown itself. On the plus side, because it will be some time before the shell is finally painted, I’ve got lots of opportunity to track down any issues like that and deal with them. Also, I will be drenching all inner structures with Dinitrol ML cavity fluid and 3125 wax - that should prevent anything nasty surfacing. The ML in particular is very runny and can get into seams - which is absolutely what you want.
My opinion- use Enviro-Strip, or go for media blasting and manual stripping of some form.
