We added a 700+ sq. foot addition. We want the interior to be a lodge/log cabin look. On two interior angled walls, we want to put old (50yr +) barn boards and have chinking between for the log look. I've been told spackling compound would work, but we're not sure of the long term effects.

The Perma-chink compound is quite expensive and this seems a good substitute because of it being on interior walls. Should we have any concerns of using this method?...or does anyone have other suggestions. Need reply asap!! THANKS
