Spray some paint in the cap and let it tack up. Spread it on the low spots and let dry. Sand flat if you have to. That's the only way I know to fill low spots with something that won't burn or melt off.
Makes sense. Fill, sand, fill, sand, fill, sand until I'm happy with it. I forgot to mention that I got the cast bear feet with it, too. Think I'll paint those, too. Silver, like the tree's?
