So i finally got my labels printed and they are slammin! And i get home and I'm like yes it's on now im about to take over the sauce game. I go to shrink wrap and im using some black shrink wrap. Now my only experience in shrink wrap before is shrink wrapping CDs and i use a heat gun for stripping paint. When attempting to shrink wrap the bottle top, it looks all kinda distorted. Any special way to shrink wrap the top of woozy bottles to make it look smooth?
