We are experiencing high humidity which I know does not go well when trying to paint metal. Anyone have the problem and solution for it?

Thinking a heat lamp and fan will work to stop dew from developing between sanding, the bare metal oxidizes almost immediately, plus the humidity plays havoc with trying to apply masking tape etc. Not sure of how the fan and heat lamp with effect drying paint.

I've always experienced too heat and fast drying causing orange peel I think they call it.

I painted my fiberglass hard hat last winter and put it by a fan and a regular bulb and the paint all rippled and looks funny.

Now here's someone who is cool, calm, and collected. Calls a hurricane that passed through 'high humidity conditions'.

Humidity is a problem for primer due to it being ports and it absorbs the water as soon as it is laid down. No fix just climate control! You can shoot some exotic paint in high moisture climates but the expense is exorbitant and the procedures mind numbing. For best results if you must paint is thin it down and add hardener to your primer and paint so as to have it dry as fast as possible, the result will still be not in line with the quality of paint you will get in a better environment but will be okay. If your talking about piss cans then the issue is null and void because the result will always be sub par due to the nature of the application.

Did and done, heat lamp>fan worked. No orange peel, blistering, or other indication of trapped moisture. All good but, not going that route again. Sealing and ventilating the shop next time, with a/c running.
