1. Is DACOR the manufacturer or is PST the manufacturer?
They were made by Pressed Steel Corp (PST) it is not uncommon to see the exact same tanks with USD on the also.
2. Are these hot-dipped galvanized tanks?
One most defiantly is. The other with the resistant coating most likely is also as there does not seem to be any rust showing through. The un-galvanized tanks I have seen all have at least some spot rust and blistered paint.
3. Is the beige layer an epoxy layer
Most likely, now that it is open to the light you may see some chalking of the primer from UV exposure. If you want to paint them and if the primer is as adherent as I think it should be, use red scotchbright to abrade the surface, do a light prime coat to active the surface, and topcoat as you think fit.
4. Is it safe to assume that the tank is galvanized underneath this layer?
See #2, if you want to be sure, lightly sand a small area to see if you hit the zinc layer.
5. What kind of blue paint did they use that it came off like skin?
Most likely some type of early polyurethane. The yellow paint on USD tanks is like it but I never had the paint come off as easily as this skin.
6. Which would be a better (at this point, easier would be nice) route: Try to get the cream tank gray again (by removing the cream layer - assuming it's galvanized underneath...) OR just use a nice white coat of paint to get both tanks matching
(appliance white. some rustoleum)
In my opinion, anything you get out of Home Desperate will suck for tanks. When I painted my tanks, I used chromated aircraft primer (MIL-PRF-85582) and aircraft top coat (MIL-PRF-85285) gloss white. This system should last many years, if not longer then I will (it is the US Navys coating system for aircraft). Outside of the aircraft industry you cant get these. If you want a good paint job, then go to an automotive supply house and get a high quality primer and paint system from them. Dupont Imron is a nice system, just let them know that it will be applied to galvanize. You can call Dupont and ask what to use. Last, make sure you dont get a clear coat system as then you will have to add a third clear gloss layer.
