Clearing Chrome

It hasn't been a year, but I have more info on this.
The POR-15 product I used yellowed after only a few weeks. It also started peeling. I contacted them to see what I could do. And yes, I should've asked them how to do this before I did it the first time. (DOH!)
I was told I used the wrong product, and didn't prep correctly.
Here are some photos showing, in order:
-The wrong product, that I used previously.
-The correct products (stripper, cleaner, metal prep and two part coating.
-The result after applying the correct product.
I thought about spraying, but brushing was simpler and good enough for a driver.
