In a past thread, I read about someone using a syringe with heated grease to inject into the boots or dust seals. Another thing I find works good is a Deluxe Cajun Injector ( www.brucefoods.com ). The injection needle has a sharp piercing point and the marinade, or grease in this case, ejects from an elongated slot in the side of the substantial needle. As you can tell, this unit is constructed to inject marinade into meat so it handles these greasing jobs just great.

Food for thought.
