I took me 4 days to read every posting on this amazing thread. Being a virgin to restoration I have little to add except one FYI regarding Decals and use of Ink Jet vs. Laser printers.
I use to repair Laser printers and Laser toner is basically powered plastic, which would be why it is more fade resistant than ink. So with a Laser printer you are printing plastic on decals.
And YES decals, like any unrecommended printer media, are best to try when your fuser is its coolest (when you just turned it on)
