mine are made with mnf watermelon . It's the closest I can get to the real thing . My recipe is 4 oz soft plastic 2 tbl of flour salt and somewhere between 40 to 50 drops of colorant . However I have a pint of m n f watermelon drop count might be diff. Add blue flake to taste . Me , I like it really blue so I add a teaspoon or so of small blue flake. FYI it's also the base for yami watermelon seed, watermelon red and watermelon no flake. If you have the original you can hold it up in the light and see the color through the light it you match that with your bait you are making. Assuming all things being equal I.e. Your mold being Identical to the original your bait color will be close when you hold it in your hand. These are my humble opinions and tweeking it is part of the fun !
This is hands down one of my personal favs as far as color goes. But it would be doing you a great injustice if I didn't say that I have mixed that color strong and mixed it week and it still catches fish! Yes adding salt will make the color less transparent. Personally I like both of there colors
Tight lines!
