How to Remove and Reuse decals ????

Can anyone teach me or help me how to remove decals so i can reuse them??

I need to rework 2 kits n want to use back the decals for the new paints...

It cannot be done. You can remove decals, but removing them will destroy them.

I removed decals before.. but the model wasnt clearcoated and i didnt use decal softener on the decals. I simply dipped the model in warm water and let it come off.
