I agree - I had to install about 150' of 2x8 PT headers for a CB stem wall - I stored 'em covered (with plenty of air space) for 6 months, and there was no warping. As for painting, I have some 4x4s installed as supports for a second-story bay window and a balcony. I pressure washed, painted with primer, then two coats of latex. No issues after ten years in the Florida sun...
