Tips on restoring a bathtub? Best course of action?

[David Czech]

A tub in my unit has had paint chipping for the last year. I have tried using the paint sealer that's available in Home Depot, but it only seems to last around 8 months before it start chipping away again. The chipping isn't terrible, but it's noticeable. I just feel as if its going to get worse over time. 

I've heard that you can have a new tub cover measured and installed that goes over the existing tub. Is that a viable option and is that expensive? How does that compare to the spray on sealer that is professionally done? I have tiling around the tub and not ready to do a complete demo. Thanks in advance!

The professional spray-on sealer you are referring to is called glazing. Glazing a bathtub lasts a long time as long as you take care of it. You can also glaze the tile in a shower if it's outdated instead of re-tiling, which is much more expensive.
