the silicone and saran wrap is the best method to use you dont need any sealing tape at all that does everything at once.and like was said here if you just want to hide the gap to wing then use the triangle stock wet down,that does make the fit look neat.be careful looking for bath tub calk at the hardware store some of that stuff is latex,make sure it says silicone,it even comes in colors so you might find a match to your covering or close.
