I have just purchased a 60's home with wall to wall carpeting, but it looks like there are some really nice hardwoods under the rugs. I want to go all hardwood. I have done this in the past, but always struggled with removing the tack strip from the hardwoods w/o scraping or denting the hardwoods underneath! I would love some suggestions. Then after that is done, what should I use to plug all the nail holes? Thanks in Advance!
