Painted my new bed sides and tailgate while it was pouring down rain. Back when I first learned to paint, this was considered a no no and I stilled believed that to be true. But the weather forecast in Austin is rain/high humidity for the next week or more. Did a little research on the web and decided it would be ok. No apparent ill effects and most importantly, no dust or bugs! I might have to paint in the rain exclusively from now on. I allowed extra flash time between coats.
