The big problem with clear nail polish -- as with all proprietary products -- is that you have no idea what's in it. And even if you should be able to find out, since it is proprietary, it may change with every lot or batch. A far better choice is the use of Acryloid (Paraloid) B-72, a conservation quality product. You can purchase it from University Products (product 039-1000; 800/628-1912) for about $5.50 per oz. Too expensive? You can purchase it as a bulk solid from Conservation Resources (products SY-7A, 250 gm or SY-7, kilo; 800/634-6932) for $10.00 or $35.00 respectively. The solids are soluble in acetone, toluene, and isopranol. Keep in mind that regardless of what you use, you must obtain a Material Safety Data Sheet (yes, even for the fingernail polish, since it is being used in a manner inconsistent with normal consumer use) and your firm must comply with the Hazard Communication Standard. If you also start storing acetone, toluene or isopranol on site you will need a flammable storage cabinet to comply with most fire codes. As to "saving on cost," we're talking pennies -- certainly the heritage you are cataloging is worth the extra effort and protection.
