Both will work. But I like the solid Alox.
Another Great Solid Lube...
4 ounces of Castor Oil * you can buy this in 4 ounce bottles at Wall Mart..
1 ounce of bees wax melted
100 grains of liquid or solid Alox * I like to cut the solid and weigh out what I need Then melt it down. When I use the liquid, I put a plastic medicine measuring cup, like you get with cold medicine. Put that on the scale and then zero the cup. Then weight out the liquid, and give it just a touch more then what you want because all that sticky liquid never seems to come out of the cup. This also makes a great lube.
I use the cheap micro wave plastic dishes ... Glad makes them.. and I melt the beeswax and Alox together after it has been weighed. Once it is liquid and hot.. add the liquid Castor oil and stir that together. It makes an excellent patch and conical lube.
