I am ready to apply my  decals on a D-19 they are maple-hunter vinyl cut Windex or soapy water is recommended but for chrome back decals they say apply dry I have done other decals dry but these are very large I would like to be able to  work with them a little for proper placement and get all the air bubbles out ,they are to pricy to mess up, how do you guys apply  these large decals  Thanks Tom

I've used canned glass cleaner with alcohol. The alcohol is supposed to evaporate out.

windex has grit in it, use soapy water (light in the soap)

well I used the "gritty" windex on all the smaller ones on the D 15, but got all frazzled out and saved the big ones for another day.

It was not easy finding that video on the Jensales page. I found it by googling "Rachel decal Jensales". She did it using only soapy water and a hand squeegy.

If you aren't sure about making your own water and soap mixture you can use "Sticker On". I have used it for half ton pickup hood size decals with no issues and the solution does not leave a residue under the decal like soap and water so you can hit them with a pressure washer and they don't lift.

You can buy a bottle of decal solution from an automotive paint store and it is probably the best product for applying decals. Second would be AC Delco glass cleaner. I know a couple of professional decal and stripe people that use it and I have used it as well. Alot of the canned glass cleaners leave a slick film which won't let the decal set but the ac Delco stuff doesn't. If your decal set didn't come with a squeegee you can use a plastic putty spreader to apply. Spray bot the metal and the decal then you can set it and line it up. Take the squeegee and start on one end and start swiping across to push the fluid and air out. Should you get a bubble that you can't flatten out you will need to take a razor blade and carefully slice under it then push downward to get the fluid out. If the decal has paper on the outside let the decal sit for a few minutes after working the air and fluid out, start at a corner and peal the paper up the then fold the paper flat the other direction and pull straight back. I usually follow the paper with my squeegee to keep the decal down. A heat gun can come in handy too on big decals.
