I especially love free caulk. Click here to get a sample of GE's new caulk singles. Mine arrived yesterday and I'm eagerly looking for a reason to use. I've already done my sink backsplashes, but if yours need redoing, this would be a great product to use. According to the website you need just one packet for this type of job. Let me know if you get one and tell us what you use it for.
