Q: Does it work as well with aluminum

8 days ago
1 Answer
  • A: Yes, Permatex Liquid Metal Filler works very well on aluminum, but you must properly prepare the metal surface first. Because aluminum naturally forms a thin, slick layer of oxidation upon exposure to air, the filler needs physical texture to bite into and create a long-lasting, metal-tough bond.

Q: Is this conductive?

18 days ago
1 Answer
  • A: Howdy neighbor! This product is chemically a vinyl resin-based filler and adhesive, which means it is absolutely not electrically conductive. While it dries to a metallic sheen and looks like metal, the cured formula acts as an electrical insulator and cannot be used to bridge circuits or replace traditional soldering.
