Metal-Etch Gel is a phosphoric acid metal conditioner specifically designed for pre treatment of bare aluminium, galvanised Iron and non ferrous alloys such as brass, copper and bronze. Metal-Etch Gel will clean and condition the metal surface to promote good adhesion of paint. Metal-Etch Gel has been formulated as a viscose liquid/gel to provide better hold on vertical surfaces. Shaking or stirring the container for 1-2 minutes will liquify the METAL-ETCH for a more fluid application. By allowing the container to stand for 1-2 hours, the product will revert to a gel.
This product is also an excellent rust remover on steel.
