treatment was supposed to be done at lear. after assembly and welding, before the foam and seating surfaces are assembled. the replacement seats are lear, just with the anti-corrosion treatment applied. my 11/2012 build car has no rust problems, its limited to the production run from feb 2012-aug 2012 if i remember the tsb correctly.
