"Just make sure whatever you line you think about it first- it doesn't remove very well."
That's the reason I have not tried it yet. We just think grinding rust is difficult, can you guess what it would be like to remove that stuff? I want to see what it looks like in different applications and how well it holds up. I have seen it used under the hood and on areas that are not seen from the outside and I will probably use it there. I will wait until I see other applications.
