Steel Wool rusting?
Hi, I'm applying matte water-based polyurethane to my douglas fir table.
Up until this point I've been sanding between coats with steel wool, BUT, I just read that this is a bad idea, because the steel particles can get trapped in the finish and eventually rust. Yipes!
It's still too early to tell, so I will proceed as usual without the steel wool.
But has anyone had this happen before, and how bad was it??
If so, should I sand back and start over at this point?
