Hello Listers

For all of you that collect irons I have a couple questions. The first one is I know some people seal their iron slices with a clear coat lacker, now is this safe to do if done right, and if so, what is the producted used. If someone wants to take it off the clear coat what can be used? Could acetone be a good agent to take off the coating?

Second question what do people use to etch an iron. I have seen some videos but nothing talks about the acid used or the strength or I must have missed something. Also if there is some lite rust on the slice, whats a good agent to clean off the slice before etching. Why I aske is because I have an iron that is etched on one side and on the other side its kinda etched with some cool looking saw marks but could be etched more. I would like to have both side etched nicely and see what peoples thoughts are.
