I spray an industrial aerospace heavy duty epoxy that comes in over 50 colors most clients choose white the best way to get rid of those jets is to cut them out and seal the holes then refinish the entire tub as you can see in this photo i posted.
With the valves closed or not run the jets on high for 10 or 15 minutes or until debris from the internal plumbing stops washing into the water in the tub.

Dealers manuyfacturer may have replacement plugs designed for taking the ports jets out and replacing them because depending on jet nozzle design and materials might be tough to get a good seal with a plug on the tub side.
