Restoration Shop UR70 Urethane Reducer Gallon — Mid‑Temperature 70–85°F, Professional Spray Viscosity Control

Restoration Shop UR70 is a professional-grade medium urethane reducer formulated to thin automotive urethane, enamel, primer and clearcoat systems for reliable spray performance in 70–85°F conditions.

This mid-temperature reducer helps coatings achieve the correct spray viscosity, controlling flow, leveling and flash times when ambient temperatures fall in the 70–85°F (21–29°C) range. Manufactured in the USA, UR70 is engineered for compatibility with Restoration Shop and Custom Shop paint lines while remaining broadly useful with many other urethane and epoxy systems. Use it to tune material body for better atomization, smoother coverage and predictable drying behavior in moderate shop temperatures.

How does UR70 change paint behavior during application?

UR70 lowers a coating's viscosity so the paint shears more easily through a spray gun, producing finer atomization and an even film. Proper reduction prevents runs and fisheyes while encouraging uniform wetting across panels.

• Improves atomization for smoother spray patterns
• Helps eliminate orange peel and promotes flow-out
• Adjusts flash time so layering and recoats are predictable
• Reduces risk of sags by matching reducer to ambient temperature

Which paint systems and jobs is UR70 compatible with?

UR70 is formulated for a broad range of modern automotive coatings: acrylic enamels, acrylic urethanes, urethane basecoats, urethane primers and clearcoats. It also works with many epoxy primers and other brands of urethane systems, making it a versatile choice for restorations, refinish shops and custom paintwork.

• Designed for Restoration Shop and Custom Shop enamel/urethane products
• Effective with urethane primers and epoxy primers
• Suitable for basecoat and clearcoat thinning in mid temperatures
• Can be used to blend viscosity across different manufacturers' coatings

When should you choose UR70 over other reducers?

Pick UR70 when ambient and surface temperatures are moderate—roughly 70–85°F—so coatings dry at an intended rate without premature skinning or extended tack. For cooler or hotter conditions choose a slow or fast reducer respectively; matching reducer to temperature improves finish consistency and application control.

• Ideal for standard shop environments in spring, summer and mild climates
• Use when surface temperature and air movement are within mid-range limits
• Switch to faster reducers for high heat, slower reducers for cold conditions
• Helps maintain consistent spray pattern when daylight and shop heat vary

How should UR70 be used safely and effectively?

Follow coating manufacturer reduction ratios and gun setup recommendations—mix incrementally and test spray on a panel before full application. Work in a ventilated booth with appropriate respirator, gloves and eyewear, and store the product according to label instructions to retain consistency and performance.

• Start with manufacturer-recommended ratios; adjust by small increments
• Test spray on a disposable panel to confirm flow and coverage
• Use appropriate PPE and booth ventilation during application
• Store sealed in a cool, ventilated area away from ignition sources

Who is this for: UR70 is intended for professional refinishers, collision shops, restoration enthusiasts and custom painters who need a reliable, mid-temperature reducer to fine-tune viscosity for urethane and enamel systems. If you work on automotive, motorcycle or marine coatings in moderate climates and want predictable spray characteristics with broad product compatibility, UR70 provides a practical, workshop-friendly solution.
