Putting a decal on 'face down'?

Hi everyone,

I came across this issue in my last model kit, and it's coming up again in my new one. The model requires the decal to go onto the clear part with the 'face' of the decal making contact, not the underside of it.

The last kit required it for the back lights of a car (Aoshima's Delorean). The manual said that I should first apply the lights to the clear piece and THEN glue it to the car body, so that the decal is 'sandwiched' between the clear and the car body. I didn't listen and just put the decal on the body and the clear over it, which seemed to work fine.

My new kit (Revell's Ford Shelby GT-H) requires again the speedometer decal to go onto a clear piece with the colours face down, not the usual request where the underside of the decal makes contact.

Is there something you guys use to do this? I tried to invert the normal decal process (by applying it facing downwards) but it doesn't work. Just asking. 

Any and all help appreciated.
