Barbeque spray pain is just the thing, then. Mask up the bike & spray away. Don't even have to take the exhaust off the bike if you mask up properly. And its cheap.
"bbq spray pain" is symptomatic of holding up the large barbecue grill while "her indoors" spray paints the barbecue! It becomes a huge pain! The resulting pain is lower in the posterior and makes bulbous extrusions commonly referred to as hemorroids!
