Rick, Is my experience with some coatings that although products 'fortified' with either epoxy or urethane can offer certain bennefits of durability or finishing qualities they still strip out fine. I look at it as being fortified is similar to addng a particle to a matrix if that makes any sense. I think it is different then chemically changing or catylizing a product throughout such as in a 2 part coating system. Disolve the main solids matrix during a strip and you then have your emulsion of suspended solids. If main solids are metal crosslinked they can be more resistant to chemical attack is the way it was always explained to me. Such may also apply more so on exterior waterborne products as they are usually tuffer to break down than run of the mill interior ones. As example, exterior waterborne acrylic for concrete is good stuff these days and is hard to remove a few days in with standard stripper.
In floor care I regularly mix qualities of certain fortified products to achieve just the right balance to suit a specific amount of traffic or preexisting maintenance practices as well as the`overall look or finish and response over a long period of time which involves constant cleans and burnishings. On interior work I try to be like Timex. Is different on exterior deck surfaces though.
