We decided that we were tired of looking at the 1969 style brick fireplace in the middle of our house. As long as I am going to put some effort into painting it, I might as well take care of that stoooooopid lip on the left side that does nothing but collect dust. Got out the angle grinder with masonry bit, shop vac and went work.... (also used the respirator, goggles and ear muffs - that was a mess.) I also had a scrap from the carpet install, and was able to patch the missing piece just fine.
I did open the sliding door and put the 24" shop fan on high to blow out the dust.
Now, time to replace that carpeting......
