I am considering ordering some Bison decals for a DAK Tiger I.

I have earlier tried some markings from the Bison "Grom" decal set and they seems to leave a nasty heavy film that Microsol set or flat varnish cannot remove/hide. Maybe I have just been unlucky as the Bison decals are supposed to be on extra thin film.

Do Bison decals need any special treatment?

Have anybody encountered similar problems?
