When I got a body job done on my van, I got the shop to paint from the top of the wheel wells down with straight silver metallic paint. The first time I saw it after the paint job, it looked like chrome and I couldn't see the break line between the polished aluminum trim around the wheel openings and the paint from 40'. That was mostly because of the lighting, but I did get a lot of compliments on the paint scheme.
Try straight silver auto paint and clear coat from a paint supplier. The silver for matching the manufacturers silver is usually mixed with other colours. It's not the same as chrome, but it looks great and you can hide the dings well.
