How to paint tub surround walls?

"They" said the walls would never yellow, but they did! Now we're stuck with them. Literally, they are glued to the walls! I was wondering if I could use rustoleum spray paint for plastic to whiten them again. I know about the tub and tile epoxy, we refinished our tub with that. Huge tub and oooollllld, don't ask, but I was hoping there was a quicker, easier, fix that would last. Haha, I don't want a lot, do I! Thanks for your knowledge.
