A friend won a Gold Medal and an other very well respected trohy with his model
But you should have seen what it looked like after being steamed, fortunately unpainted..
The superb paint job covered the singe marks, and went a long way towards winning the prizes.
If you don't mind an unpainted model acquiring any sort of patina, leave "as is"
So the choice is entirely yours. If others don't approve, TOUGH.
Your model, your choice.
