I'm repainting the walls and trim inside my house. I have about a gallon of the old paint (alkyd, satin sheen) that I'd like to use to touch up dings in the baseboards and walls. Is is likely that this paint will still match the old paint color-wise? How can I tell if the paint has "gone bad"? Or should I just bite the bullet and buy some new paint and pray that it matches the old color well enough to blend in?
Thanks,
Jean
