Spraying outside ?

[trebor]

I know it's a bit late in the year but I've got to do some primer to stop panels going rusty now the weather has changed So i know I need a dry day and not a damp, rainy, shit horrible day. Is there a rule of thumb to go by like outside temp and humidity to prevent damp getting under paint which causes the first frost to pimple the paint from underneath ? Reason I'm asking it's happened to me before when I had an old mk2 Capri years ago. I'd sprayed this in a warehouse as well :?

Primer will not help as it is porus.

I've still got to spray engine bay with top plus lacquer. I have a plastic greenhouse to use as a cover and an oil filled electric radiator to heat it.

Buy a heat gun to warm/ dry the panels first & to help dry your primer off too!??
