It's a 2 part epoxy putty that's workable for 30 mins or so then dries rock hard after 24 hours, apparently it even dries under water.
It's really handy for making those hard to find parts👍
Just about all model shops stock it.
Sorry for the messy bench, I'm having a busy afternoon lol

Thanks Wayne.That will help me a lot with filling in the interior of the Rica. What I have picked up are about ten one inch model China teddy bears playing instruments who will sit in the Rica. if you blow up my profile picture you will see figures and a bar on board. it gives my boats character and the Spainiards here love them.
Buenos dias
