Not sure what caused your pan to go from non-stick to sticking, prompting you to apply a manual coat of seasoning. When pans are stripped to bare iron, and a coat of seasoning applied, they're still a good ways away from the non-stick of a well-used piece. When using a pan with just a base coat of seasoning, you have to use a little more butter or oil to keep things from sticking. Cooking bacon, sausage, and the like are good things which accelerate the build-up of a good slick layer of polymerized fat.
When you applied the Crisco, did you wipe it down really well before baking it? Putting on too thick a layer at once can leave the pan spotty and sticky. If trying to build a good seasoning layer manually, it needs to be multiple extremely thin coats individually baked.
