I don't know if this is the right subreddit but idk where to ask for help on the subject. My shower is made of metal and is very clearly an add on to make the place an apartment. The landlord painted the walls and floor of the shower though and it's chipping like crazy. There isn't ventilation in the apartment but I crack open the window when I can. I really want to just "re-do" the job because it feels icky even if I clean the shower. Is there a paint stripper, paint, and sealant I should use to do it? I'm worried about telling my landlord because I don't want him to act like I'm damaging the apartment or something. I swear I'm literally just showering and cleaning it.
