What can be used to mark a queen?
It just occured to me: as it is "white" year may I use liquid paper (whiteout)?
I don't think white out will last too long. Testors make model paint pens that work quite well. You can get them at most craft stores.
Thanks Robo, forgot about those stores.
Enamel paint pens are what I use. I buy them at the hardware store.
Good tip Robo. I have used fingernail polish in the past. Practice on drones if you are not sure of the reaction.
