I'm doing some face lifting in the bathroom and we removed a large "glued to the wall mirror" and are replacing it with a smaller framed hanging mirror. My question is that there is a fat drip line you can see where the edge of the old mirror met a paint job.
Is there a way to remove it with thinner or something similar if I'm planning on painting the whole room anyways. If there are no other clever ways to do this, I was just going to sand it down and retexture the orange peel which is kind of a pain, but it seems like if I just got some paint thinner or similar and rubbed a small amount on the line I could smooth out the paint, prime and not have to sand/re-texture. or is that asking for peeling/adhesion problems later?
