Super, super job!Actually, I am a thoroughly incompetent DIYer but I wanted the floors to look better and didn't want the disruption of a major pro job so I HTFU'd and did the work. If I can do it, you can do it. Just be careful.
Good grief, I looked on Amazon and found hundreds of 2 part epoxies. Do you have a suggestion about what to get and do you buy clear and then add dye or buy epoxies with a dye? If you add dye, is it something special or just the stain I used on the floor (or maybe a little darker)?
... Here's a video from a woodworker that I follow. He knows his stuff. The video is not for a floor, but you'll get the general idea how to epoxy your gouges. ...
Great video. It might be too late now, but if donheff saved some of the sawdust, that might make a good filler with the epoxy? Though it probably would not take stain once it gets an epoxy coat, but maybe if the epoxy is tinted first, then some sawdust added?
The gouges don't look that big to me, I would think he can get by with one or maybe a few hardware store sized packs of epoxy?
