Hello all, Thank you for the replies!
Monty Python script:
This is not the Removing Decal Department.
This is not the Decal Replacement Department.
This is the Cover Over Decal With Another Decal Department.
Refer KitMaker Topic: “Removing Decals”
My question: Have you ever covered-over an existing (in situ) decal with another decal? Were there acceptable results or were there adverse effects?
Fellow lurkers, you’ve left me no choice but to perform the “medical experiments,” myself… I had Igor go out and dig-up (order) the ‘U.S. National Insignia for soft skins’ set from Archer Fine Transfers. The plan is to spray-up a sheet of styrene, paint, gloss coat, blah, blah, blah. Then, I’ll lay-down one of the older Dragon star decals… MicroSet, blah, blah. After which, I’ll overlay the new (larger) star to witness the outcome. Stay tuned for my report… 
Cheers!
