They were bulletproof: epoxy was for chemical and mechanical resistance; polyurethane for UV resistance (epoxy will 'chalk' in sunlight). All in titanium white.

    Quick search of their site was no-joy on the epoxy - maybe discontinued, or renamed? Poly is still available. Excellent products!

    Mr. Thompson, I am not promoting this for use on your porch, rather just anecdotal endorsement of the brand. But.... if you want the be$t, $-W Indu$trial Coating$ will get you there.
    We’re currently having some paint warranty work done on the dome of our courthouse (I’m the maintenance tech there, the dome was repainted about 4-5 years ago). There were various processes used based on the prep regimen (which was based on thickness of the metal substrate and cost). Anyway, on the thicker metal, it was “vapor-blasted” back to bare metal, a clear, 2-part, epoxy primer was used, then a tinted, 2-part epoxy intermediate coat, then a 2-part urethane topcoat. Where the prep and process were good, the product is near bulletproof. However, there were some holes missed that rusted, among other things like a rush to beat impending winter or deadlines…hence the warranty work.

    could it be the bare metal wasn't pickled before the clear epoxy was applied?

    I've been using Emerald since it came out.

    I don't even use the combination paints on interior work.

    Yes, I know it is stupid expensive. Its like $70 a gallon. But we did major prep, two coats of primer (one heavy, one touch up) and two coats of finish (again, one heavy and one touch up) and that was 2006 and the whole house looks perfect.

    Tip: Twice a year your commercial Sherwin Williams outlet will have a 50% off sale, usually in the Spring and Fall. If you sign up for an account, they'll let you know ahead of time. At least in our area, one has to have a commercial account (not too hard to set up, just lie if you're a homeowner), and drop in every month or two and ask when it will be. Once they tell you an approximate date, I started calling them every week to make sure I got in on this. Our house is huge, takes like 200+ gallons, so the 50% off sale really makes a difference, and it is the best paint around.
    Regards,

    Just getting on SW's email list will get you 20-30% off from time to time...but yes, it's easy to set up a commercial account and that also gets you access to some coatings that are not "supposed" to be sold to mere homeowners, like the A series products which are quite good for the money.

    It seems like about every other month they have 30% off, and a couple of times a year 40% off.

    I'll second the commercial account at Sherwin Williams for better pricing and access to "professionals only" products. My husband's business has an account, mostly for caulking, but when I made a VSCT fence system I was able to purchase an oil-based "professional" enamel paint that wore like iron.
