Ladd,
As an opinion, and making some assumptions....
1) If you are covering with old decals, before[i] removing[/i] the decal from its sheet, then I would use a Krylon Clear Acrylic Satin Clear or even Krylon Clear Acrylic Coating (slightly heavier). A laquer such as Deft Clear Laquer will work but sometimes does not keep a brittle decal intact.
2) If the decal is fresh,can be water soaked and applied intact, then, when dry, a thin layer of laquer should work fine. If it can be applied with an airbrush, all the better, The idea is to preserve the decal and protect it from minor abrasions.
Good Luck,
Tom Sanders
