Was your lid completely missing? We have a 189 Sport where they were present but severely sun damaged. We cleaned, lightly sanded, and painted with 4 coats of Krylon Fusion in charcoal gray. It ave it kind of a hammered finish look. We tried the silver color at first but it was much lighter than the factory stuff. Where we ended up is darker but looks better.
The guy who owned her before me decided to drill lots of holes in her. I guess for a CB or something. The compartment holds water pretty good now. I found a replacement at the stealership. $$$$$
