It is a wood filler at a very good price. It is easy to work with. If it doesn't sit well on the spatula and slips, we wet the spatula to add moisture to the filler (not too much) to soften it and apply it without any issues. After it dries, it sands easily. It works great for small holes, openings, or gaps that we have removed from the wood. However, in my opinion, it is not suitable for large openings. In those cases, a filler with glass fibers may be needed, or personally, I also use foam filler, which is more expensive but does the job for large holes, etc. The foam filler just requires a little practice to get used to working with it.

It is a bit tight and may be difficult in some areas. That's why personally I dip the spatula, the stock remover, in a cup of water that I have next to me and then I take the stock with the wet blade of the spatula to soften it. If needed, I lightly spray the stock and mix it. I do the same with the foam cutter (it is difficult for me to work with it without wetting the foam cutter or the blade of the stock remover - spatula). This little trick helps me.
