I am working on a rocking horse for my nieces christmas present. I have it painted with white acrylic craft paint and it is made out 2×10 pine from lowes. I would like some help in choosing a finish that will not turn the white a yellow color. I have used zinsser bulls eye clear shellac on my previous projects, but as they were not painted I never noticed a yellowing of the finish. If anyone knows if the type of shellac I am using will turn the rocking horse a yellow color, then please offer a suggestion of a finish that you have used that has not turn white paint yellow. Thanks for any help and Merry Christmas.

Any shellac will yellow the white paint at least some. I have the lightest color available, platina, and its a bit yellow. A good paint is all you need (dont know about the stuff you used). If you still want a clear coat, GF hp poly or Target em9000 are water clear waterbased poly’s. No oil or solvent base finish (except some industrial types) will cure water clear – all have some yellowing.

I don’t think those “craft” paints are very durable so….
I vote for top coating with a clear water based polyurethane. Two or three coats. Watch for runs if you brush it on.
Second choice would be a spray on enamel (the shaker can type).

CAB lacquer from Sherwin Williams is a solvent based finish that dries clear and does not yellow.

When you put a clear finish over paint you have to consider the possible changes (yellowing) of both the finish and the paint. When I worked for NASA we spent a lot of money for a “non-yellowing titanium white paint” to use on spacecraft to be landed on the moon. Then Apollo 12 landed close enough to one of the landers to check out the changes after 2-1/2 years. The paint had turned tan.

Your rocking horse may not be in such a hostile environment, but it WILL likely change color over time.
