Yes! It is sealed with a breathable reactive penetrating sealer.
The frames are made from 1/2" x 1/2" hollow Stainless Steeltube. We cut and tig-weld each part for each frame per order.
Stainless steel is extremely rust resistant - however if a blemish starts to develop, it can be buffed out with stainless steel wool or a grey-scotch bright pad.
