Dennis, you are quite obviously a convert, and have had a different experience, I tried POR15 at least 10 years ago and was not satisfied with the product for my purposes, and yes I used their metal ready rust treatment first, I am simply relaying my experiences and will stick with what I know works for me and stays that way longterm. Others my choose to follow your example, if nothing else our conversation will highlight the need to be absolutely scrupulous with preparation, if I am slack in this respect I am slack with other paint systems too, but I have had good results on many paint jobs. I have a chassis wire brushed and painted with Hammerite in 1984, other than a few stone chips it is still perfect, interestingly rust has not spread under the edges of the chips either. I stopped using Hamerite because a, the formula changed and b, because I now have even better results with 2k. I learnt to paint cars in the early 80's using Cellulose, that is no longer an option here so I tried Acrylic and enamel lacquers, neither were really to my satisfaction, the suppliers suggested 2k and gave sound advice, so today I use PPG or Delfleet with excellent results.
