Is it just oil based paint/gloss that yellows due to lack of daylight?
I posted a few months ago about my white gloss in the hallway yellowing very quickly, since then I've found out it is because it gets no daylight, or very little. So despite sanding them down & repainting they are yellow again! (have been using oil based paint)
Going to use a water based paint this time, will that still yellow? Also do I need to strip the other stuff off completely or just rub it down?
