I've had strange reactions myself when plant applying solventless urethanes to transmission pipe when at a certain time of day (just before sunset) the moisture in the air supercedes the isocyanate reaction, thus producing high density foam. We introduced a steam jenny into testing lab in MInnesota to duplicate heat and humidity of Houston (solution was to change the catalyst.)

We just applied PPG's PSX 700, a siloxane system, to a steel boat trailer. The substrate was blasted to a near white metal. The humidity in the shop was 42% which is very close to the minimum recommended y the manufacturer. We were very impressed with the ease of application, the way the coating flowed and the low VOCs. We will add a second coat then do some destructive testing on our sample. We are hopeful but the real test will be seen over time. I would likely add a zinc primer next time. Does anybody have similar experience or input?

I think the zinc system will perform better. If you add a second coat, depending on recoat time you may consider scuff sanding and solvent wipe prior to recoat. I have had some bridge experience with that same system. I like everything about it you mentioned however when the contractor did not perform the necessary surface prep during "touch up" the second coat delaminated from itself. i.e. the polysiloxane won't stick to itself w/o a little prep first.
