[QUOTE="GreekIslandLover, post: 25338, member: 1566"] Hi all, Got asked a question by a freind, and am looking for what you guys think. He's putting something or other (12v - all the info given) outside in the garden and I gather it's aluminium cables somewhere along the line. I know there is a chemical reaction between the two metals, and his concern is that this will cause poor connections somewhere down the line. He's been on the web (groan) and found a product in the USA you smear on the terminations to stop this reaction and he was wondering what we do here. "Use copper cables and brass" was my answer. So, on the very limited info above, is the chemical reaction really a problem? Should he be investigating products to import from the USA for a few garden lights (making an assumption based on garden and 12v)? Should he not worry? Should he skip it, and buy something with copper cables instead? Have asked for more info on precisely what he's up to, but would appreciate your thoughts on the scant info I currently know. [/QUOTE]
