Painting a suitcase - rust on the latches - what to use?
I have a fiber board vintage suitcase that I cleaned and painted with ASCP this morning. After the first coat, I noted that the rusty latches on the case, that I had sanded first before painting, had orange speckles coming through the paint. What should I use to fix this and stop the rust coming through my chalk paint? I was wondering whether to use a shellac based primer, such as Zinsser Bin, or use something such as Minwax polycrilic on the latches to prevent the rust bleed through? Thanks in advance.
