Read the technical bulletins Dale. I've talked to many tech support people at nearly all of the vinyl manufacturers, and they find that insufficient squeegee pressure is a leading reason for installation failure.
I wish I woulda thought about it, I would have asked you to demonstrate installing graphics to a vehicle using your products while we were at SGIA. It was a pleasure meeting with you briefly, by the way. I'd love to see a video demo.
Don't get me wrong Dale. I think your products are great and serve a purpose. I just don't believe that wrap installation is anywhere near one of them.
I think we are on different channels. The Big Squeegee is not designed to work with complex curves as you will find in most wraps. However, I have installed graphics on door panels with no other finishing pressure and had no problems with failure.
Actually, someone did come by my booth with the same questions. I had a table that the vinyl would not stick to so I was challenged to lay a second layer onto the first. I past the challenge with flying colors. I had one other person test the bond after applying to Coroplast. He too, was satisfied with the results.
It don't take much to do a test on your own.... Lay a square of vinyl on any substrate with the Big Squeegee, use a little squeegee to set one of the corners. Let it set for an hour at room temperature and check to see if there is any difference in how hard they are to remove. You should be using heat to set a wrap so any difference may disappear with that part of the operation.
I don't recommend air release channels be used with the Big Squeegee. They do take a bit more pressure to set the vinyl and may trap air as the result of air being trapped in the channels during application. Air release vinyl requires enough pressure be applied to reform the glue.
Repositionable vinyl will work much better.
Perhaps, some installers are wanting to use the Big Squeegee to smooth down large areas of a complex curve. This is not the way the tools were made to work and I agree that it is no place for it. The Big Squeegee is designed to work on a flat surface and apply the vinyl across the entire width. Using a smaller squeegee to install large graphics is not recommended. Some people do it with a fair amount of success anyway.
