Mixing, ratio, temperature and gel time - the plural-component basics that decide whether a lining bonds or blisters, taught on real substrate rather than a slide deck.
Polyurea, polyurethane and polyaspartic side by side: where each belongs, how to build a system from them, and the detail work at terminations, joints and penetrations.
Reading a resistance chart properly - concentration, temperature and immersion time - and choosing a lining that survives the chemical actually stored on site.
Profile, moisture and contamination. Preparation is where most coating failures are decided, so this covers the testing that proves the substrate is ready.
