R-M Paint Systems

Maximum Innovation

There are two things that count for painters: using the best materials and saving as much time as possible. That’s why we judge all our innovations by how they measure up to these standards. The results speak for themselves: easier application, better covering power, higher gloss, faster drying times, outstanding finish and improved environmental compatibility.

R-M History


For 100 years, R-M has been one of the automotive industry’s most innovative brands. R-M pioneered numerous industry firsts, including Florida weather testing and the first tinting base system.


    Early Years

    Founded in Detroit in 1919 by Fred Rinshed and Herbert Mason, Rinshed-Mason, later known as R-M, immediately became an iconic presence in the automotive industry. Cadillac was their first customer.



    R-M launched the very first metallic finish for cars in 1931. In the 1960s they were trusted to provide heat-resistant black lacquer for one of the first space missions. BASF acquired the fast-growing company in 1986 and, by 1988, R-M had become the leading refinish system in North America.



    In 1996, R-M led the industry as the first brand in the automotive industry to launch a website and put all of its color formulas online. With its unique blend of innovation and BASF chemistry, R-M continues to be an industry icon and a paint brand preferred by thousands of body shops throughout the world.



    R-M Onyx HD is the only paint system that can be mixed as either waterborne or solventborne with a single set of toners. It meets all VOC regulations in North America.

BASF’s product portfolio includes products for multiple industries. A product that is compliant for one region, industry, application or end use, may not be compliant for another region, industry, application or end-use, and BASF accordingly disclaims all representations, conditions and warranties of fitness for a particular purpose.

To assist automotive refinish customer searching for information about BASF products that meet the VOC limits for automotive refinish use, BASF provides Wall Charts that list the products that are compliant with the automotive refinish VOC regulations in specific regions in North America (country, province, state, air districts). It is the responsibility of the purchaser/end-user to ensure they know and understand the regulations for their specific region, industry, application and end use and ensure that the products that they are using are compliant with all applicable regulatory requirements and any permits specific to their business.
