Tony I built my first trolley top with a full copper top in 2009... It wasn't until I'd almost finished that someone mentioned the reaction between the two metals ... There is a bonding layer separating them ...but I was mindful that when it rains the water will be a conductor and cover both metals ...For whatever reason there has been no detrimental effect from using the two dissimilar metals ....The first trolley top still belongs to my daughter and lives outside all year. This is it at one of the shows we attended this year...
