IIRC, there is a "Hospital-grade" paint, for germ repelency . It was an enamal I believe....Anybody ever refinished and painted a toilet seat? The price of a new one is about $60.00. I would rather take it off , sand and repaint. Anybody have any experience with that?
Or, you can just replace the bowl...maybe even for free. When boat yards and dealers "upgrade" toilets, they often pull out brand new ones and almost always just scrap 'em. When I still owned a business, every fall or winter my local yard would let me take 2 or 3 bowls to have on hand in the spring to be able to provide cheap replacements for people who'd discovered that just pouring antifreeze into the bowl and flushing it didn't protect the bowl. Even if I was 100% sure a bowl was brand new, I still power washed it and rinsed with a strong bleach solution.Next time you are considering replacing your compact pump assembly, instead replace the whole toilet with a "household size." You will be much more comfortable.
