As Duke36 quotes from the DeAngelis book, lower body colour first, then accent upper colour. These guys were professionals & would have been very quick.
Pin stripping was done after body paint was dried in oven, & before being put on the chassis . Era films of Model A's being assembled show the stripes on the body when it is dropped on the chassis. In other eras [ Model T or V8] it may have been done different.
