I saw where someone used appliance paint on the outside of their tub. Is this possible to do with the shower surround? Is there anyway to improve one other then replacement? Thanks

I would not use appiance paint but Rust-o-leum and others make a tub and tile paint. The fumes are very, very strong but the finished product is going to last many years. RustOleum.com

Thanks for the advise. It was very helpful.
