Does anyone know of a durable polyurethane that will not leave a yellow tint on white furniture?

I just painted a dresser white and I am ready to apply some sort of protectant coat over the finish. The problem is I also used a crackle finish so I am not able to use a water based clear coat because it may disturb the crackle. Does anyone know if a good brand of oil based poly that actually goes on and dries clear? I am really concerned about it leaving a yellow tint on the furniture as I have experienced in the past.
