I've been using Tru-Oil to finish my bows for the last 7 or 8 years,like many of you do.It makes for a great water-resistant finish,thats only weakness,as for as I see,is contact with insect repellant.A small bottle will afford enough 10 coat treatments to finish many bows.The last bottle I bought back in february,is still half full.I put a first coat on a new bow last evening.I went out this morning to apply a second coat,but it was still tacky.The RH for our area is no higher than normal,in fact I've applied it while it was raining outside without a problem.Have any of you ever experienced a "short shelf-life",with Tru-Oil? Appeciate any comments, Thanks, and God Bless
