Duratec® Reducer is the perfect solvent for Duratec® products. This specially formulated thinner/reducer is made from urethane-grade solvents as opposed to standard lacquer thinner. It matches the original solvent cut, assuring complete compatibility. Duratec® Reducer enhances flow and leveling properties and reduces orange peel and porosity. Using this thinner allows for reduced air pressure, which reduces overspray and allows for a smoother spray flow.
I will never use Duratec again. It sure flows real good but about 10 years later the gelcoat was falling apart like house paint. Thankfully I only painted the transom.
