Looking for a durable, weather resistant, resin for outdoor use.
I've got a DIY project I'm working on and I could use some advice.
We're repairing the ornamental railing on the outside of my parent's old house right now. That kind of pointless ornamentation some old houses have along the edge of flat portions of the roof. Specifically these are little onion shaped wood topper bulbs screwed into a wood beam that runs along the edge of the roof.
Originally they were wood, but this is in Texas and the weather here has a tendency to just destroy any wood that isn't properly treated. And these delicate little wood onions didn't stand a chance. I'd personally just leave them off or find something similar pre-made in polyurethane or similar, but there's a historic society thing happening here and I have to replace these with identical decorations.
I've done some resin casting in the past, and I got the idea that maybe I can make a mold of these little ornamental things and cast in a extremely durable resin. But I'm not sure what kind of resin would be the best fit for these.
Can anyone recommend a really tough resin that can withstand intense heat and rain? They'd be painted.
Thank you.
