I’ve got a small metal shed to paint, with a couple large areas of extreme rust. Normally I would not mess with this, but it’s on rental property for a very good customer. She understands this is not going to last forever, just wants a couple more years til she replaces it.
Just to see what would happen, I used a wire brush on a drill and got the surface rust off. The bare metal still has some rust spots. The paint store is suggesting laquer thinner, spot prime with oil and paint.
I’m planning that plus some light coats of DTM. I don’t want to spend too much time on ths, but I’m open to suggestions.
