Here's a video of side hinge, on glass, in the cold (according to www.accuweather.com it's 28 degrees when I made the video).
Practice, practice, practice. That's the only way you'll get better.
Cliff notes of the video:
1.) Side hinge
2.) There are times when you can't do things wet or just doing them wet would give you a headache. Mainly compound curves, recesses, reflective vinyl (trapped water can cause delamination), vehicle wraps, cold temps
3.) Practice isn't expensive. Use some scrap! For the cost of one bottle of a popular application solution, you can buy a whole 15"x10 yard roll of medium grade vinyl!
4.) It's all about squeegeeing technique. It's a swipe or "slicing" motion. Easy and smooth and you won't trap air.
5.) It's fast and effective. No cleaning up application solution.
6.) No worries about contaminating the adhesive with improper solutions (some degreasers, perfumes, dyes can hurt the PSA) and no worries about pH problems.
7.) Being able to use both dry and wet application makes an installer more versatile.
Sorry the video cut out. I kept talking for about another minute. My camera has a 3 min limitation on video and I didn't hear the beep. You didn't miss much, just me peeling off the application tape. Came off in 3 pieces (it was high tack paper after all). Then I went to clean up and take that vinyl off the glass, it was stuck down so well it wouldn't come off! Since it was cold it was postage stamping (tearing off in small pieces). I had to get out the scraper.
Enjoy the video!
