Hi again,
Thank you all for taking your time and reply, much appreciated.
I did not express myself well, my actual concern was if a setting solution (Tamiya or any other) would be strong enough to actually pull the decal all the way down into those deep "pots" that Revell has provided in the plastic IP.
I experimented a little with smaller pieces of the decal, lettering I wasn't going to use and had to give up, the bits either turned into drum skins or licked to the side walls of the "pots" and became unreadable
I had a "trusty old" Micro Sol bottle in the stash and tried that on the larger decal and that worked out OK.
I then tried cutting out the larger dials and place them in their "pots" but the tiny bits were so quickly affected by the solution they just crumpled and folded into unusefull blobs.
Guess the old Micro Sol bottle is exactly that - old.
Something has happend to the solution since it actually lifted the paint.
You can see the effect on the seat framing on the right in the picture, that is Tamiya paint dried for more then 3 days.
So now I am waiting for the Airscale sheet to arrive, will try a new bottle of Micro Sol together with that after I have tested the fresh solution on the paint.
Thank you for your comments and advice!
Stay safe all!
Svenne
