Body Work and Paint Estimate

We switched to Dupont waterbase a few years ago and now everything has dirt in it. It dries too slow! It also shrinks like crazy so you may not have orange peel today, but you might 6 months from now! I had some small pieces painted with it and man... not happy. We are switching back to Sikkens very soon as they have a new product that is EPA compliant.
To ask a question, are you talking about the HS clears shrinking back later. Just trying to compare to my own experiences.
