It is my first time using liquid mask, any tips or links to help to make it a successful first time would be greatly appreciated.

4 coats and you will have no poblems
use a knife with a round cutting edge. easier to cut complex curves out and easier to manage cutting force. too often ill score into the body. you cant really see until after you peel the mask. takes a while to get the cutting touch to not scratch and get through the mask. quite versatile, but requires some practice for sure.
Careful not to score the body. But, if you don't cut completely through the mask, you'll make a huge mess.
