I’ve been using Timbabuild products for a great number of years, on and off. I’ve never been able to find a fine surface exterior filler that stood the test if time. So….. when I came across Finish, the selling point was 2 part filler. Experience: good value but a far from perfect product.I have, so far, used 5 tubes and, without exception, from mixing to gardening has been some 4 minutes!I’ve wasted about one tube, out of the five through product going hard on the mixing board before I could apply it all from the single mixes. Each mix was about 1/6 to of the tube. Applied product fine. Also, the first sanding clogs the paper VERY quickly. All of which, 2 stars.
