When you guys run crown, do you cope your inside corners, or just 45 it. I've been coping all my life, and these days most jobs spec out MDF, which is cuts like hot butter with my coping saw. I usually end up caulking my insides anyways, so why not just 45 the inside corners with fingerjoint, paint grade or mdf? It would save time. Also, I have a RIS which tastes great, and is not over carbonated. However, when it hit the glass from the bottle, it foams aggressively. Any other explanation other than an infection? Have you experienced signs of an infection like this without off flavors?
