" Acetone is a solvent based alcohol .. "  - No.

" Spray cans don't always atomize the best and stop spraying after a while - especially RUST-O-LEUM brand paint!!  " - No

" I only use thinner when I have to spray a light coat that is not meant to be touched ever once assembled. "  - WTF

" Trust experience over hype "  - OK

Decanting aerosol spray cans is far from efficient  -- aside from the monetary end , you're boiling off solvents that are a portion of the mix that factor into the performance of the paint  ( not talking about the propellant  , I'm talking about solvents like butyl acetate etc )
