I would like to write following:
There shall be no damage or cosmetic defect to/of/on PRODUCT.
Damage to, damage of, damage on?
If different prepositions are used for "damage" and "cosmetic", is it then possible to write them together separated by /:
There shall be no damage/cosmetic defect to/of/on PRODUCT?
There shall be no damage to, or cosmetic defect of, product.
