Im looking to put just a piece of a cut up coke can in. Is it something I should coat first? Thanks! March 7, 2014 at 6:58 am #562 Katherine SwiftGuest Hi Keir, The aluminum can should do fine. It wont take up water stains if it gets wet, so it should cast well in any kind of resin. Author Posts Viewing 1 reply thread The topic ‘Aluminum’ is closed to new replies.
