I just bought a house and putting new baseboards on. I read and heard it from a few people to use 33 glazing compound on nail holes so I went out and bought it. I was under the impression that I could also fill in big cracks and gaps to mold and sand to look nice. I'm on a tight budget so don't really want to have to buy something else but will if I absolutely have. So can I use it for that or no?
