I opened up a wall in a friends kitchen, and I need to add about a foot along the cut end of "click lock" bamboo flooring for about 12 feet, around 25 planks or so. I think my two options are to either take up the entire floor but un-clicking it and putting longer planks in, which he has because I'm taking it out of another room. Or I hope I might be able to weave longer planks in by cutting out the last plank in each row, and sliding in a longer piece. Since I can get to the end now that the wall is removed, I imagine tapping gently on the end to insert it between two other planks. I know I won't be able to lock in the short ends, but I may be able to lock in the long tongues this way. I hope I'm explaining this well enough. Any help is much appreciated.

We have relatively new hardwood floors (oak). We've already accumulated some deep dents from heavy things being dropped. I have researched and thought of two potential solutions, but I am not sure which is best. One idea is to scrape off the finish on the damaged section, then press a hot iron on a wet cloth into the dent to try to raise it. However, I would then need to refinish that section, and I don't know what type of finish was used originally. Would I just apply some clear Minwax with a small paint brush and hope I pick the correct one (gloss, semi gloss, etc.)? Alternatively, I could just try to carefully fill the dents with clear epoxy. That would avoid having to try to pick the correct finish. Not sure what is the best option here.
