Hello Corey, you should know caulk is washable, it isn't intended for wet areas, particularly not recommended to seal a bath.
Try and use sanitary silicone, I'm using Dow Corning 785 bacteria resistant for a couple of years, excellent quality/price.
Make sure the area is clean dry and grease free. Fill the bath half way with water before applying silicone, Always use a good quality silicone and spray a small am out of WD40 on your finger to get a professional finish.
You must make sure the area is clean and grease free use a good quality bathroom silicone also you could purchase a set of silicone tools such as a fugi kit (about £20 )
This well make the job so much easier and long lasting
