When in doubt about how to use a product, which resource is BEST to consult?

The best resource to consult when in doubt about how to use a product is the manufacturer's instructions. This is because the manufacturer provides specific guidelines tailored to the product, detailing safe usage, application techniques, and any precautions that should be taken. These instructions are designed to ensure that the product is used effectively and safely, allowing the technician to understand exactly how to achieve the intended results without risking harm to themselves or their clients. Manufacturer's instructions typically include essential information that reflects the company's research and development, making them the most reliable source.

While other resources like the Material Safety Data Sheet (MSDS), online forums, and colleagues can offer valuable support and information, they may not always provide the targeted details needed for a particular product. The MSDS focuses on safety information related to the product’s ingredients and handling, but does not delve into application methods. Online forums can give a range of opinions and experiences, but these may not be reliable or applicable to every situation. Consulting colleagues can be helpful to share experiential knowledge, but isn't as authoritative as following the specific guidance provided directly by the manufacturer.
