Maybe try wet blasting to keep dust to a minimal.
I've heard a lot of good things about that "Dustless Blasting" co., if anything is available in your area.
I hear you can rent the equipment and blast it yourself.
As for chemicals, only thing I have found is that taking the coarsest sanding disc you can find ( 24 grit or so ) and quickly scratching up the old CARC will create weak areas where the stripper can get under the paint and be more effective, but yes, try to find some of the old Aircraft Remover stuff. If it burns your eyes nose and skin like sniffing straight ammonia, then you got the good stuff... if not, the you got the EPA compliant crap that will barely strip fresh rattle can paint!
