I just had my bathtub refinished, it looks GREAT!
Unfortunately now the rest of the bathroom looks like shit.
I could have had the bathtub re finisher do the ceramic tile walls (original 1937 tiles) but his price was too high. I thought I could handle the walls myself.

What suggestions do you have for a product that will cover the tile walls that leaves a high gloss finish similar to the original ceramic finish?

Homax makes a kit that is sold at Home Depot / Lowes. It's like a two-part spray can, IIRC. When it says wear a respirator, it means it.
