How interchangeable are add on Zimmerit kits? Will a Tamiya set work on a Dragon kit, etc .... ?
Not a dumb question at all - there are no dumb questions, just dumb answers.
I recently used a Cavalier zimmerit set meant for a DML Panther A on a Takom Panther A and had no problems. Provided that the various kit manufacturers have made their models to the correct dimensions (something which some Tamiya kits in the old days did not), you shouldn't have any major issues.
