my unit's bathroom window lintel started showing rust spots roughly 6-8 months ago (moved in 2 years ago) so I decided to see take action and try to remove the paint so I could apply a rust converter followed by rust guard epoxy enamel top coat to protect it after (white knight products).
However i've been having difficulty removing the paint that is already on there. I tried to scrape it and use a metal brush but after a good 30min or doing that I barely removed a small portion of it (see pictures below, the right side is where I tried to remove the paint)
Is the best approach to use a paint stripper to easily remove the paint? I'm also a bit concerned using paint stripper indoors in terms of dangerous fumes/chemicals in a small closed space as well as smell in the rest of the unit.
Also this unit is from 1973, any chance this paint contains lead?
