At the suggestion from this forum, I used Apoxie Sculpt. It was a bit of a learning curve, because I’m used to GreenStuff from my miniature wargaming days, and you really do need to let it sit after you mix it for at least 5 minutes before you start using it. Still, I like how it isn’t too hard to work with after 10 minutes, and I’m sure I will learn to be better with it. I can really see the advantages if I ever need to do a larger repair – if I need to do a lot of detailing, it will be a godsend.
