Just joined the forum. My shop is aircraft related and we are looking for the best way to polish and seal 2024, 7075 clad aluminum. We plan on trying the ZoopSeal we bought thru Eastwood but really need a way to polish the material first. Tried Mothers Mag and Aluminum Polish which does a fair job but need something mechanical-based to really generate a miror finish. Clad aluminum has .003-.005 pure Al on it’s surface and we should be able to polish away minor scratches etc before we seal with Zoop. Would appreciate any ideas out there.
