This may not be the best place to post this idea, but for those of you who have white tambour doors in your AS or Argosy may have found them turning that ugly old banana yellow. Just remove them and use Krylon Fusion white satin spray paint on them and they will look like brand new. Get enough on them to do the front surfaces and that will generally do the V spaces between the slats. It does not look at all like they were painted as the fusion paint does just that, fuses with the original surface. It holds up very well. That same Fusion paint will do the plastic refrigerator vent, and the old yellowed end caps of the units made up to about 1974 or 5. If your AC interior cap has yellowed, take it off and do it too. It makes a world of difference in how old the interior looks.
