When ya said stripped and treated I take it you meant with phosphoric acid. Most DTM High Builds are known as hybrid epoxy. I used this type primer frequently years ago. No longer my preference. Be careful because these DTM primers don't adhere on top of acid. I have never had the bad experience but have seen it happen. They will peel. I prefer just regular non-acid base epoxy over acid and under urethane high build or polyester primer. Just my opinion and food for thought. :happy1:
