The best thing about the clear vinyl to me is it doesn't change the color of FL Yellow or FL Chart like SH does. I have used it a long time if I paint eyes on a jig for the 2 colors mentioned above. If you use SH over the 2 colors it will change the color every time to something undesirable IMHO. So have always used it for this. Even though it takes time to not just dry to touch, but to cure good it does take time.
