I have a question about refinishing old doors. I am currently in the painstaking process of striping off about 7 layers of paint from my 100+ year old interior doors. While the process is long and tedious, the results are beautiful once I have all the old paint off, sand, and re-stain the wood. However, I am finding that some of the old doors have large and small holes in them where hardware was added and then removed over the years. So, I am trying to find a REALLY GOOD WOOD PUTTY or filler that I can use to fill the holes; one that will also absorb the stain so that the holes are less noticeable. Can anyone suggest a brand of wood putty to use?
