I'm about out of the current bottles I have, which are/were LMM-6060. Before I buy another bottle, is this the best version for marking Stainless and the most economical? I remember reading posts about the new formulations are not as good as the old and so on, and I'm not sure what variation of Cermark that was... but I can't seem to find those posts now and wanted some input before I order a new batch.

Thanks!
