My wife is not happy, and I kind of get embarassed myself when an admiring person in the Home Depot parking lot waits for me to leave, and I see him waving the smoke away from his face as I pull away.

Is there an agreed-upon additive that minimizes this effect? If not, just say so, and I'll stop complaining about it.

The additives are a waste of money. Pull the head off and get it redone.
