I just had new windows installed in my home. They are double hung, the bottom one slides up and the top one slides down. My problem is that I have white trim but the sash that the windows slide up and down on is a beige color (its also plastic). I'd like to 1) paint the plastic white and 2) do it in such a way that it is durable enough to handle the windows sliding up and down. Thanks for input!!
