It dries hard and solid..

On a related topic, Undercoating would have been done after fuel line and brake lines were installed, but before the drivetrain, correct?
I’ve had undercoating on the fuel and brake lines, on the gas tank and exhaust shields, upstop bumpers for the axle and is on the wiring for the front side marker lights, but it is not on the drivetrain components or the K frame.
Is that accurate?
