Installing Avery Etchmark

Is Avery etchmark a material that needs to be installed wet or dry? what is the best way?

I need to install this material on 5 windows, 50" high. the roll is 48" wide so I was just going to roll it across the window, but this material is a LOT thinner then I expected, and flops all over the place. I cut a 4x3 section to fit into the window between the sides, but since it was a bit wider then the window, the top portion was not coming off properly.

I went over hto his shop to do a test fit, but it did not work out well at all. ALL other jobs I've done have been smaller, these windows are 33"x48" and recessed into a frame (which is dirty, and has to be cleaned before)

if someone has some tips to install it properly, it would be appreciated. I really messed up the test one, because the right half I tried dry, and the left half I tried wet. I had first tried to hinge it from the top, but the sides folded over when I tried to roll it up.

Should I cut the vinyl exactly to size? or should I cut it larger then the window, then squeegee it into the corners and cut?

 

yes, it will be spotless. I pointed out all the areas he needs to clean and told him I will be spending an additional 15 minutes per window to clean it better. at first those windows were horrible! you think that is bad? the original owner had painted the windows, then glued styrofome to them!

What do you mean by float it off?
