I'm good with that plan--just let me know all the details (paint, number of covers of each color, addresses, etc.) Weather has been good, so I can paint whenever it doesn't rain. I'll probably do 3-5 per day for sure--but we'll see (sanding will be the slowing factor--painting itself doesn't take long): could be more. I'd probably do it in batches (sand all the covers for white, paint white, while white dries sand covers for red, paint red, etc.) I would wait around 3 days before shipping out--depends on the kind of paint I'd use. If it's oil, it'll be stinky for the first week or so, because oil takes some time to cure, and when a cover will be all wrapped up in packaging material, all the evaporation will be trapped in the box during shipping. So if enamels are what will be used--don't be surprised by the oily / chemically smell for the first few days!
P.S.: I know you guys have been waiting a long time, so I'll take a bunch of photos to show the progress.
