I use those full sheet shipping labels, get 100 of them on amazon for 20 bucks, print and stick. They are really hard to peel off unless I use a hair dryer softens the glue and it peels right off, leave very little residue nothing a light hand sanding won't take care of.
I used the painters at first, it does great but at times can lift off or stick to well and on luan peel off the veener, I have ruin good projects due to this, shipping labels I have not ruined one yet since the hair dryer softens it to let it peel right off.
