I used the BIN primer from ZINSSER. It has a shellac in it. The owners before smoked and this is supposed to keep the smoke smell in the wall instead of in the house.
The good news is that it seems to have worked and the primer has gone on with the consistency of a semi-gloss paint. No residue comes off when I rub it either with my hands or a rag. Is there anything wrong with keeping the wall as is and not painting over it?
