The paint can be sensitive before applying the protective coating, so use care when making your designs. It’s important to finish up your shades by applying the protective coating provided. This will help seal in your design and keep it from getting even more scratchy.
Additional Tips & Tricks:
Once you’ve created your design and placed the protective sticker on, use a blow-dryer to adhere the protective sticker more securely. This blow-drying technique will ensure stronger adhesion to the paint/glasses and will also allow you to “push out” any bubbles that may have been created while applying the protective sticker. No need to over do it, this technique shouldn’t take more than 2-3 minutes using the “hot air” feature on your blow-dryer.
