We usually start a few inch leading edge by hand and run them through a cold laminator if it's a basic color change and nothing has to line up. If you have borders or elements that need to be placed in a specific position we use a light table to make the placement and weights to hold it in place while we start the leading edge.
The only problem with the wet application is the wait time to trim. You should wait a day or so before attempting to trim because it will just lift on you. I personally never really like to wet app, only as a last resort.
Side note, I really don't understand why there always has to be at least one person that talks about "common courtesy" to provide more information and then proceed to complain. If you don't know what they want, simply ask the specific questions you need answered to provide help or just move on. I'm new here and am trying to give a little help as I've received some and just want to give back, but it's really irritating to always see this post. Do people just copy and paste this in every thread just to be pricky???
