the main problem when the decal is dry.it pry lost.will not stick to the model.and I am not talking about old decal,these decal are new.

There are several brands of decal solution to fix the problem.

You may look around for these:-

1. Microscale - "Micro Set"
2. Tamiya - "Mark Fit"
3. Gunzyo - "Mark Setter"
4. Humbrol - "Decal Fix"

Just a few examples, not exhaustive.

A trick I've used is to dip the decal in Klear/Future once it's off the carrier sheet, then apply it to the model. Wipe off any excess with a wet-wipe. For difficult shapes use a hair dryer (carefully).

I do like this:

1- Future or Humbrol Clear Gloss (same same to Future),to prepare the surface
2- then set the decal with help of Micro-Set
3- Micro-Sol to blend de deacal on the model surface
4- Future or Humbrol Clear Gloss to seal

never have any problem on this way

Never heard of doing it that way, but it sounds like an elegant solution (no pun intended). May have to try it myself.

The hair dryer technique does indeed work, but this should on be done only on model surfaces with no delicate plastic parts in the area. The small parts heat and warp very quickly and often in areas you don't know are being heated.

I've heard of people using a hot, moist towel to press the decal down. This is usually done on Tamiya or other Japanese manufacturer's decals.
