This worked very well so I was able to seal the tub and railing. This allowed me to achieve something that doesn't look homemade. It looks like it was done by a pro. The only thing I want to do (and this is my fault, not the product's fault) is use masking tape to make a clean edge on each side of the bead. That way, when you're done, you can peel off the tape and get a nice line. I ended up having to use a razor to trim and scrape. I recommend using tape and avoiding scratches.
