Review (1/5): Not needed. Dont help adhesive.
I dont think the primer is needed. It supposed to be waterproof. This isnt waterproof. I applied it to try it before my trip. And in 3 days my lace slid right off. It wasnt even my workout days. Ill stick to gotstobe glue. Plus it leaves a sticky white film on my lace that was hard to remove. The remover smells like goo-gone within oranges in it
