Surface Preparation Tips:

For optimal results, ensure surfaces are thoroughly cleaned and degreased using OS fluids, naphtha, mineral spirits, or methyl ethyl ketone (MEK). Avoid solvents like acetone or isopropyl alcohol (IPA), as they may not effectively remove oils. Light surface abrasion is recommended to enhance cleaning and improve bonding surface area. A final wipe with acetone or IPA can help ensure a clean, ready-to-bond surface.
