It's important to sand for the right amount of time when using Trizact discs! 👍 We always recommend doing 5-6 overlapping passes in a north-south, east-west pattern. This helps provide even coverage for the working area and helps make sure you are removing very fine defects in the painted surface. And yes -- Trizact discs should be used damp! Not dry, not soaking wet -- just slightly damp. 😊 https://s.3m.com/4s0tx98w | 3M Collision Repair
