Is water based polyurethane any good?
A well-engineered, water based polyurethane will be equal in clarity to oil-based polyurethane.

This is ideal if you want the natural color of your wood to remain constant..
How do you seal white paint without yellowing it?

How do you fix yellow Polycrylic?
To solve the yellowing, when the Polycrylic is just tacky (almost dry) spray a light mist of 1 part vinegar to 10 parts water and wipe off with a clean cloth. The yellow will wipe off leaving the finish clear. The yellow will not return when the Polycrilic dries. Use a non yellowing polyurethane to prevent this.
Why is my white paint yellowing?
Light, and lack of light, can affect how well paint color is preserved and how quickly it yellows. In the case of yellowing due to lack of light, chromophores are to blame. Chromophores are produced as oil-based paint dries, and are a natural part of the process. Chromophores are broken down by exposure to light.
