Bests & Worsts Reviews from Amazon

I have used this product on a number of projects, and have found it to be a great tool in the arsenal. It is only for paint grade work, and has a few characteristics that you must be aware of before you use it. === The Good Stuff === * The product is great for larger repairs I use it to hide countersunk lag bolts, or to repair gouges or knot-holes in wood where a smooth appearance is desired. * The product sets up pretty quick, and depending on the thickness of the repair, can be sanded and painted fairly quickly. A quarter inch thickness will dry in less than an hour, and can be sanded and painted immediately. It sets and dries quicker than the one-part bondo filler available in tubes. * The product will shrink a bit, so really deep repairs may require multiple applications. I never saw the product crack, and once you have a smooth surface, it seems to hold up both indoors and outdoors. I always paint and prime as soon as possible, so no idea how well it will hold up unpainted. === The Not-So-Good Stuff === * The downside of the quick drying times is that you only have a couple minutes (maybe 2-3) to use up the product once it is mixed. * The instructions are fairly specific about how to mix the product. To be honest, I cheat, and just mix the compound and hardener just enough to get a consistent color. That seems to give me an extra minute or two to work with. I seem to get away with it. * The filler comes in a large can-sort of like a quart paint can. Since the filler is a thick putty, it is a bit of a challenge to get the last 10% out of the can. * Consider using disposable plastic putty knives- it is a tough job to get the dried product off of metal tools. === Summary === This is a great product for hiding any number of sins and problems with paint-grade wood. It dries quickly and hard, is easy to sand and paint, and holds up well to use and weather. However using it is a bit of a challenge, and requires you to work fast.
