Repair dip in bathtub

[cspringer]

Hi,
There is a slight oval dip in the middle of my tub that is approximately 6x12 inches. The water settles and has discolored the area. I'm not sure if the tub is cast iron, steel, etc. (not fiberglass). Is there an epoxy that I can use to fill in the dip that won't pop off after a year or two? If not, any recommendations for a DIY (spray paint) fix?
Thanks

You probably have a steel tub that is dented...

Not much you can do with it except replacement.

Thanks. I was afraid of that.

I did find this link but after checking out the fix on cars (youtube) it doesn't look promising. I guess it's worth a few dollars for a can of air just to satisfy my curiosity.

Any recommendations for painting? I see a lot of products on google but perhaps someone has experience with a particular brand.

E-How is useless for information on Plumbing...
They are a content farm that produces useless articles on everything and relies on advertising clicks to make money....
Unfortunately they come up in searches and often above sites that have much better and more credible information.
Google hasn't figured out a way to knock them down and bring the results of better sites up yet....
Their efforts to do so have cut the traffic from better sites as well...
