They come with paper backing that is on the TOP of the decals, and a peelable plastic backing on the BOTTOM of the decals.
So, you cut them out, then peel off the plastic backing, place the decal down on the surface, with the paper backing up, then soak it for a minute with a wet sponge. Then you can peel away the paper backing. No sliding of anything needed. And the decals are super thin and fall into every nook and cranny. I don't know if I have any extras I can send you of those.
The other decals, I will send you a ton, but only if you are serious! I don't want the stuff to sit there and have nobody DO anything with it, that's my fear.

I have no real comment on Aeroloft, except I called some years ago to buy an F-89 kit, and I remember being really turned off by the person on the phone, acting like they were doing me some really big favor by taking my money, so I did not take it. I don't think I have ever used the actual product, though.

I have always felt water transfer was better. Especially high quality water transfer. And there are big differences between the cheap thick decals and the really good ones. The really good ones lie down like paint over rivets and panel lines. Also, you need Microsol sometimes.
