I have a 17 year old pine log home. The interior caulking has shrunk in spots, there are also some small holes that are letting in cold air. I just purchased some LogJam as that is what the contractor says was used. It is in tubes. My hands and wrists cannot get tired and sore very quickly from using a caulk gun. Would a small battery operator caulk gun work okay for this job? I am hiring a log home contractor to repair the outside caulk and restain it this Spring. .
