I have not tried that Eastwood product, but I am surprised as well. I loved their spray can rust treatment, but I have to say that for whatever reason, no matter how hard I tried to clear out the cans after each use, they pretty much always gummed up and would no longer work after just one or two uses. Maybe I just didn't do it right, but their quality product is expensive, so I had to give up on it. Also, I tried to get them to send me new nozzles, but that was back when COVID was still a big deal. They were apparently in a mess at that point and never fulfilled their promise to send them to me.
