Roberts,

I had the same questions about Koverall a couple of months back. If you enter "Koverall" or "Butyrate" in the search you will find a wealth of information about it, as well as input on the same threads from folks using Nitrate dope.

I have completed finishing my plane with Koverall, dope, and primer. I went through almost an entire gallon brushing and spraying solely Butyrate dope in the process. It looks great, and I am proud of the finish. But personally, where others have used Koverall and love the stuff, I HATED working with it, and will avoid a doped Koverall plane in the future. -That's just my experience.
