Restoration Shop Urethane Reducer Gallon — UR70 Mid‑Temp (70–85°F) for Automotive Paints & Clears

Restoration Shop UR70 Medium Urethane Reducer is a professional solvent formulated to thin urethane and epoxy coatings for spray application in mid-temperature conditions (70–85°F).

UR70 is a mid-temperature reducer engineered to bring automotive paints, primers, and clearcoats to the proper spraying viscosity so coatings flow evenly and atomize predictably. Manufactured in the USA by Restoration Shop, this universal reducer works with a broad range of modern systems—Acrylic Enamel, Acrylic Urethane, urethane basecoats, epoxy primers and urethane clearcoats—helping body shops and serious DIYers achieve consistent results in temperate environments.

How does UR70 affect sprayability and finish quality?

By lowering the coating’s viscosity to the recommended spray range, UR70 improves atomization and wetting, which reduces orange peel and helps coatings level out. Proper reduction also helps control flash time and solvent release during curing when used in its intended temperature window.

• Promotes uniform atomization for smoother laydown
• Reduces risk of runs and sags by matching flow characteristics
• Helps coatings level for better surface appearance

When should I choose the mid-temperature (70–85°F) reducer?

Choose UR70 when ambient and surface temperatures sit roughly between 70°F and 85°F or when booth conditions are climate-controlled to that range. Using the correct temperature-grade reducer helps maintain recommended flash times and prevents under- or over-flashing that can affect adhesion and finish uniformity.

• Ideal for temperate shop environments and mild outdoor days
• Use when previous thinner was formulated for similar temperature ranges
• Adjust to slower or faster reducers if conditions deviate from 70–85°F

Which paint systems and substrates are compatible with UR70?

UR70 is formulated to be broadly compatible: it pairs well with Restoration Shop and Custom Shop Acrylic Enamel, Acrylic Urethane, and urethane basecoat systems. It also works effectively with urethane and epoxy primers plus urethane clearcoats, and can be used to thin many other brands that accept universal urethane reducers.

• Works with urethane and acrylic enamel topcoats
• Suitable for thinning epoxy and urethane primers for spray application
• Compatible with most clearcoat systems that require a urethane reducer

Who is this product for? UR70 Medium Urethane Reducer is aimed at professional collision repair shops, automotive refinish specialists, and experienced home restorers who need a dependable mid-temperature solvent to tune coating viscosity. It’s also a good choice for anyone using Restoration Shop or Custom Shop paint systems who wants a US-made reducer that yields predictable spray performance in temperate conditions. Always follow the paint manufacturer’s mixing guidance, observe recommended safety precautions, and test-apply when switching reducers between brands.
