Did you know you could have oily nail beds? Cause I didn't lol and I do I guess. If you have no clue if you do or not, just treat it like you do and prep one nail at a time.
File your nails and push back the cuticles. Use a buffer to dull the shine and wipe with alcohol. Let it dry. I used my blow dryer. Match up shield to your nail remembering to not pick too big of a size. It can not touch the cuticle or skin. Roll the shield off the paper and cut it in half. Heat it using your blow dryer till it softens. Press firmly to your nail. Use one of those rubber cuticle pushers. Trust me. They work the best for this. I heat once again (cause I'm paranoid lol) and press again. Trim off excess shield down to your nail and use a file in downward motion to get the rest of it. Reheat and concentrate on the edge. I even ran the cuticle pusher over the end of my nail to help smooth. Just make sure there are no bubbles.
After watching the video, I decided to redo my nails using the above method and I can honestly say I can tell a difference in them. I put these on last night. Pictures to follow.
