🔍 Key Concepts

• Difference between removing loose scale/rust and reaching into deep pits in steel surfaces • How each tool acts on high spots vs. low spots on a rough, pitted surface • Why proper surface preparation is critical before applying primers and coatings

💭 Think About

• Think about which tool can actually get down into the bottoms of the pits, not just touch the top surface • Consider which tools mainly attack loose material on the surface and edges, and which can break or chip out rust and scale from deeper cavities • For heavy, pitted corrosion, ask yourself what the first stage of preparation would be before smoothing or cleaning with finer tools

✅ Before You Answer

• Compare how a wire brush versus an impact tool would behave on deep pits • Decide which tools are best suited for light rust/smoothing versus heavy, pitted corrosion • Ask: which tool is normally used first in a badly corroded area, before brushing or sanding?
