I do it by sight. I keep peeking in and when they get that shiny, glass look I pull them out and let them cool. I usually set the oven to 350 and it would take around 15-20 min for 1/8-3/8 oz jigs.
It's a vinyl paint specifically for jig heads by Component Systems inc. just warm the bottle in hot water to thin it and put a thin coat on it with a small paint brush over your cured heads. Also, make sure you completely clean the eye of the hook before you bake....I can post some pics later after I get off work, although I switched over to vinyl a few years ago, but the pearl looks the same over the powder.
