I use Kiwi neutral shoe polish as a release agent .Clean metal parts and mask off clearances with high quality masking tape. Heat the barreled action slightly with a spotlight from aproximately 12". Use cotton patches and q-tips to apply a thin coat of wax.
Let sit for ten minutes and buff with another cotton patch.Done.
Chet Brown used a mold release wax in making stocks . I have experimented with most common used products but the Kiwi shoe wax -$2.59 Cdn /can works best and is easy to find and use.
