There is absolutely no need to go the automotive route. BM's advance is a wonderful paint. I've gone through gallons and gallons. I prefer the low sheen of satin but that depends on the piece. More modern pieces might look good with a higher sheen but the lower sheens I feel are more appropriate for more traditional pieces.
Before Benjamin Moore (BM) introduced their Advance line, I used Fine Paints of Europe (FPE) ECO extensively. I had many a conversation with the founder, John Lahey Sr. through the years. I learned a lot from him. Sadly, he passed away in June 2012 but his son carries on as President. Their colorist Emmett is top notch as is Charlie for technical advice. I'm very familiar with their entire paint line.
All alkyd (i.e., oil) paints are prone to yellowing as they age in the absence of UV light exposure. You are more likely to see it with white colors. Paints like BM Advance and FPE ECO are waterborne alkyds and will yellow as well but not nearly to the same extent as a pure alkyd. But if you're using either BM Advance or FPE ECO, don't worry about it. It will be very subtle and hard to notice. And you won't see it all if the piece is exposed to bright sunlight. The only white that will stay white is a 100% acrylic latex. But those paints are not good choices for furniture.
Fine Paints of Europe does NOT guarantee their whites from yellowing. In fact here's an FAQ on their site addressing that very issue. The Eurolux Acrylic they reference is their 100% acrylic latex.
Q: White enamels always yellow in my kitchen. Why does this happen and how can I prevent it in the future?
A: White alkyd paints, even great alkyd paints such as Hollandlac and Eco, will yellow in the absence of abundant ultraviolet light. Dark rooms create an environment in which yellowing occurs quite rapidly. This is especially troublesome in rooms such as kitchens and bathrooms, in which a yellowed painted finish presents an unacceptable contrast to white enamel appliances. The only alternative is to utilize Eurolux Acrylic, which is non-yellowing under all circumstances. Eurolux White will provide an ideal solution to your yellowing problem.
Bottom Line: It sounds like you found someone that knows what he's doing. Have him spray your pieces with Advance (my recommendation would be satin, but have him show you sheen samples) tinted to White Dove. Honestly, what ever yellowing occurs, you'll never notice over the years. And if it concerns you that much, choose a creamier white.
This is a china cabinet I restored in my own home. It was brushed with a custom mixed color in Advance. It was primed with FPE's oil primer/undercoat. I chose that primer specifically because it's high-build primer.
