I used Log Builder to caulk my log house about 12 years ago and it is still holding up fantastically. When it came time to caulk my son's house, I searched the internet again. Western Log Homes Supply seemed to have the best price and EXTREMELY FAST shipping. I ordered and received the caulk within about 3 days. I live way out in the mountains and it usually takes at least 5 days just to get a letter in the mail. Shipping was really, really fast. I've finished caulking the house and this goes on easily, smooths easily, and dries really nice. Very pleased.
