Easy application works well and blends into most browns.
This stuff works great. Seals up seals or cracks in the wood and nearly matches or blends in with most browns. Works well, easy to use, paintable and reasonably priced. Easy to apply and color matched in multiple orders from different vendors. Highly recommend this product and seller.

Really good caulk
Love this caulk. Goes on smooth, easy cleanup, cures quickly. Been using it for 15 years in the south Arizona desert where pretty much everything except 100% RTV gets hard from the sun. It survives better than most, with minimum shrinkage and cracking.
