"Yep, those look like the original lousy, corrosion prone bolts on my car."
couple of options......
- go with chrome bolts - can get expensive though
- chrome caps or color caps - not the easiest as you need to take on/off
- re-paint 'em yourself (beer bottles make great stands so get prepping

)
if going w/ chrome or just repainting yours, be sure to pick up a "soft" 19mm lug socket to prevent chipping in the future. Pelican has 'em as do other places (I think Vertex, Automotion, etc.)
