Shake can for at least 2 minutes once the mixing ball starts to rattle. Hold the Rubberized Rust Encapsulator can 10"-12" above surface as you spray. A single coat dries to the touch in 20 minutes, and is thoroughly dry in 3-4 hours at 68°F. For greater durability, a second coat can be applied 1 hour after the first. Allow 6-8 hours after the last coat before applying topcoat. Use over or under body fillers. Quart maybe brushed on or applied with an undercoating gun (like our 20441 Undercoating Gun Kit); no need to topcoat, unless desired.
