Seche Restore Thinner is the only thinner that can be used to thin a vial of Seche Vite; no other thinner can be used to thin Seche Vite.
It can also be used to restore any other nail polish product, be it one produced by Seche or any other brand.
This product will not diminish shine or dull colors and only replaces those ingredients that have evaporated from the bottle of Secehe Vite or other nail polishes.
