This particular dining set our clients actually want to use them for indoor use. They liked the brass decorative knobs so much, they asked us to keep them free of powder. We polished them up to a mirror-like shine, then wrapped with a heat resistant tape. This way, no powder landed on the brass, and after the chairs came out of the oven we simply had to peel the tape away!
We can coat anything with powder rated for exterior use. As long as you follow the suggestions in our care sheet, then your furniture should last you for many more years!
