We have a 40 year old ponderosa pine log cabin and have used a clear (Behr) Transparent wood finish about 3 times. The corner logs have turned dark grey and some of the horizontal logs in parts are doing the same. Is there some product available or inexpensive procedure after cleaning the logs to cover these portions of darkening yet keep the natural log look which we have done with the Behr product mentioned ?
