What is the first step in preparing bare metal between 1 and 24 inches?

The first step in preparing bare metal between 1 and 24 inches typically involves using a glass cleaner. This is because glass cleaner is effective for removing surface contaminants such as dirt, oils, and residues that could interfere with subsequent processes. Ensuring that the surface is clean is paramount for achieving strong adhesion in any later coating or treatment.

When you use a glass cleaner, you are providing a clean slate for further preparation steps. While options like applying metal prep or scuffing the surface are essential in the overall process, they should follow after the initial cleaning with the glass cleaner to ensure that no contaminants hinder those actions. The mention of using SP-207 may indicate a specific product for another step, but it wouldn’t serve as the initial cleaning step. Therefore, starting with glass cleaner aligns with best practices for surface preparation.
