Well, it was several months ago when we did this. The last pictures were taken today. I have run alot of water in the bathtub and sink, the paint has held up with no problems. As far as the long term, I will just have to wait and see how it does. I did this with the intention of it being a temporary fix, we will just leave until it needs redone.
P.S. If you do any sanding before painting, make sure you wipe out all of the dust. Otherwise you will not have a smooth surface. First time I thought I had got all the dust out, looked good but surface was not smooth at all. I sanded it smooth again and used vaccum and a wet rag, then repainted.
