What is the best way to resurface a one piece fiberglass shower for a medium range price?

Is this a solid colored surface? If so, then I think that painting it with paint designed for resurfacing bathtubs and showers would work. You would use a compressor and spray gun for this. The cost for this around where I live, is around $350.00 to maybe $450.00 depending on the size of the tub or shower.
