Well I tried the colorbond stuff and spot and would give it a mixed review. The color didn't exactly match, I think it's a little darker and I could have done a better paint job probably but overall I think it's an improvement. It did cover up the worn spot and it's less noticeable now. I kind of painted a bigger area than I needed to though but I still think it looks better than it did before. See pics below and it's actually not as noticeable as it seems to be in the pics...
