Clearing Chrome

I bought a set of these: https://www.cragarwheel.com/wheels/whee ... 3-smoothie

After only two months, they started rusting. I waxed them when I installed them. Every two months I've polished the rust off and waxed them.

I emailed Cragar to tell them how disappointed I am, and ask them what they would do for me. I expected a run around, but to their credit, they have agreed to reimburse me.

So now, I have a set of free wheels that still rust. I'm wondering if there is a coating of some kind that would hold up for a while, protecting them. As it is now, the chrome is just getting worse and worse. It seems to be blistering, minutely. I can't rough them up to spray them of course, as that would ruin the finish. Even if it was something that would last a year or two, that would be better than them rusting constantly, and hopefully stop the blistering.

I don't want to use a solid color. That would defeat the purpose of buying chrome in the first place. The truck that they are on is bright blue, with a chrome bumper and grill. It looks good in chrome.
