applying brown sludge to the undersides of cars

Well, I spent the better part of the last two weeks slaving under a cold chassis, and I've gone through I-don't-know-how-many of those little brushes, but, dammit, it was all worth it. There's nothing quite like admiring a well-sludged vehicle. I don't know what it is - could be the perfect mixture of brown and grey this time... maybe the way the sludge looks like it could just fall off, yet it doesn't - you do it just right, and it's perfectly balanced! This is the best winter ever .
