White oil-based paint yellowing?
 
I was told at the paint store if I used white oil-based paint it would yellow. What makes it do that and do I really have to worry about it?

Lack of sunlight will cause oils to yellow. It depends on the exact composition of the paint as to how bad it will be but pretty much all oil does it. If you have it in a closet for instance where it gets no sun you will get much worse yellowing than you will in a wide open area with a lot of windows. Is there a reason you are using oil? Oil still has it's place but it's becoming far less common than it use to be. You can add just a touch of black tint to the paint to keep the yellowing to a minimum.

That was my first question, why oil?
The new latex quality paints out there will last just as long and in some cases longer.
Far easyer to clean up at the end of the day with no hazardest chemicals.
Less VOC's.

Alkyd resin in the product is the cause of yellowing, due to a lack of UV (sunlight).

This^^^^

Over the years I have seen oil-based paint go from a bright white to a nicotine yellow.......it takes a while for it to happen, but, it sure looks ugly compared to a bright white latex.

Yes you do need to think about it.Get with the times man....lol.....with proper prep and priming you can convert your woodwork to a waterborne paint.It will stay whiter and modern acrylics are very durable.

Thank you all, there is plenty of light, it is a metal handrail, but it sounds like the acrylic will work so that's what I will use.

If it's a metal handrail use an Acrylic DTM (direct-to-metal) paint. Most brands have one.
