Review (5/5): Practice and Time.
if you've never used this before, be aware! this takes some practice. and time. but it's worth it!
i heat it up in the microwave, for about 10sec, then spread it out in a layer on wax paper to cool and reset. the cooling time is short, but the resetting time is longer, if you are going to apply at 5pm i'd melt and set at around noon to ensure it's fully set and strong enough to pull off the wax paper without tearing, also to diminish the stickiness of the previously melted product.
aside from that, i would practice practice practice! have fun with it! the more you play with it the easier it is to apply and and be creative with.
enjoy!
