The top coat seems to always have a fuzzy look and pin holes As if it's having a chemical reaction.

What are you trying to topcoat with? Are you trying to build thickness in one coat?
How long after zinc application are you waiting before trying to top coat?

Inorganic zinc will off-gas for a fairly long time during cure. If you have cold temps then it will prolong your minimum recoat times. To verify your cure, you should perform the 50 double rub test according to ASTM D4752.

I'm trying to coat it with an tnemec series 1074. I'm curing it out at 250degrees for 20 minutes but only waiting about 30 minutes before I top coat.

Why are you heating it at that temp for curing? The TDS allows for up to 140 degrees surface temps max during application. The recommended curing accelerator is 44-710. There's no reference to heating it to 250 degrees for curing. The TDS only states that it will tolerate up to 250 degree temps once cured by normal chemical reaction.

If I put the oven at 140 I doubt the paint will get hot enough to cure

You may be compromising the coating with those temps. It only allows for a 140 degree surface temp for application. This is a chemical cure coating, not an oven cured coating like powder coatings. That's why they recommend an accelerator. But none of these details probably answer your question about the finish you're getting. BTW, are you agitating the zinc urethane?

Your doing it wrong man. That is a moisture cure zinc. Heat does not help you. Read the tech data and follow the directions please.

Well the information I received has been VERY helpful. Yes we're screening it after mixing and agitating during the painting process.

If anything, mist the surfaces down with water. But the zinc needs ample dry times before topcoating, or later on in the field, your topcoat is going to blister and you will redoing your job.

The maximum range offered in the TDS for ambient temperature cure times, is 4 hour recoat at 75 degrees F. (that's without the excelerator I believe).

google tnemec 90-97 for the product TDS. And as Painter213 mentioned, this is a moisture cured urethane. It actually needs a certain amount of humidity. If I remember, at least 30%?

It's doesn't cure by heat. It cures by reacting with moisture. It is a moisture cured zinc. It needs moisture to cure.
