If you debark a stave and seal the back with TB or other similar products that penetrate the wood, does that inhibit the deepness of the stain color? If the answer is YES, then what other type of sealer can be used so that the stain penetrates deeper. Or what can be done to remove the coating so that the stain will be a deeper color?
Also, if oil is used on the belly to add backset or flip the tips, etc, does that inhibit the deepness of the stain color? If the answer is YES, what can be done to remove the oil?
What I have tried for removal is to dampen the wood with water, then slightly heat the stave (oil floats on water and TB will soften) and use a paper towel or rag to wipe off the oil and TB.
