Hobie, bt may be cheaper, as you don't have to apply it over and over. Once and it's done. AND..... As Murrell said, no more moths, and a 1/4 lb. has lasted him 4 or 5 years and he still has plenty. I bought a half lb. and have been selling it for 1.50 per teaspoon for 3 years, used it on all my frames, and still have 1/2 pint. I have all my money back, plus some. You can't get any cheaper than that.
