Ive noticed on this forum and others as well there are reports and opinions on Imperial sizing wax that range from-"better than sliced bread"--to---wouldnt use it on a barn door. My question is whether there are "batches" of the lube that are better than others --or what? Ive only purchased one tin of the stuff several years ago and Id class it as something Id use if theres nothing else around. Others use it to lube case necks for neck turning. I couldnt do that even on a carbide mandrel. Are there that radical batch differences?
