What adhesive to use ?

[green dewback]

Some time ago I printed a decal on normal a4 paper for the 7676republic-gunship.

I folded the top edge to form a inverted hook or clip to hang onto the lego plate piece.

But there is a problem, the bottom of the paper is unsecured and flaps around.

So I was thinking, maybe sticking the 2 bottom corners down for good, but I don't apply stickers anymore on my lego.

What adhesive do you guys use ? preferredly no residue or staining upon removal or degrading after years.

I have thought of double-sided tape and blue-tac, but DST turns yellow after years and wikipedia says blue-tac leaves oily stain on paper material after long period of time.

Thanks in advance.

I use Pritt, it can be removed without a trace, even after many years.

For me, a regular glue stick. I won't take it off. That's why we have BrickLink.

Thanks for the tip.

I tested with glue stick, paper and imitation brand plastic brick, peel it off after 40hours and very minor damage to the paper.

Whatever tiny residue on the plastic is easy washed away with water.

I will use glue stick then ! Cheap and effective solution, but have to be gentle as it's holding strength is weak.
