Reseal stone sink?

Molded sink that was installed in 80s. Not sure the material but its hard. Its a his and hers corner counter top so i don't want to replace the entire piece. One of the sinks had a clear coat or something that has degraded over time and it looks horrible. Is there a product I can buy and refinish the sink with? Thank you.

It looks like cultured marble or similar resin cast vanity & sink. I have never seen a "coating" used but many do have a surface skin (the pretty part) manufactured in that contains the color with the bulk underneath being a filler type resin. Unfortunately it is largely plastic and plastic (resin) can crack with age and be attacked by chemicals. Acetone (fingernail polish remover) is one bathroom chemical that will attack most sinks & vanities like that.

Minor surface imperfections can be sanded & buffed out. Look at the bottom of the vanity & sink to see if the it is the same material throughout. Since yours is white look carefully for a difference in the materials as the filler is usually whiteish. If yours is one solid, uniform material throughout it can handle a lot of sanding and buffing but if you can spot two materials (skin & filler) you have to be careful to not sand through the pretty layer on top. Replacement is really the only proper fix I know of.

Some plumbers putties are known to cause crackling (plastic) and staining like that around the drain in both plastic and natural stone sinks. You can buy refinishing kits but it may not cover up the crackling or it may just continue to crackle and damage the new finish in a short time.

40 years is a good long time, its likely due for replacement.
