The threads I used it on were for an old diesel bus I was helping someone with. It was for these small studs that held on chrome hubcaps to the rear wheel hubs that were caked in old paint. You could see fine paint chips and a few fine metal fillings sprinkle down into the wheel well I ran them, and the retaining nuts then went on smooth as butter with your fingers. So satisfying.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
