@liquidconcepts I Can get you more detailed information, but yes and no. As Jim mentioned, It hooks mechanically amazingly well. You just have to watch for flash rust if it's bare steel. Waterbased paint on metal... That being said, the 35 series can go direct to steel if it dries quickly (baked like Jim says). But... there is another line of Aqualac that has better flash rust inhibitors in them that it's only marginally more $. 38 Series I believe. Prime has some amazing guys (who are much, much smarter than me) who have helped me along the way.
We also get away with more because we wash all our blasted parts in a heated degreaser and that solution has a rust inhibitor built in. All our testing came back with no issues.
