Jim Bowen 1 Posted November 17, 2011 Noticed my rad which isn't too old is starting to corrado top and bottom, only minor surface stuff. Is there anything i can use to stop it? Not sure if normal rust stuff works on aluminium. Have seen people paint rads black before, but suspect that wouldn't last long. Quote Share this post Link to post Share on other sites
Supercharged 2 Posted November 17, 2011 Starting to Corrado - lol! Is it a genuine one?? WD40 might be the best thing over winter - anything thicker might hamper its ability to cool Quote Share this post Link to post Share on other sites
