Why would you mirror shine the whole upper? It will crack and look crappy as soon as you walk in them.
This is why I was asking if you had pics of the "Travers method." I think you are doing way too much to your shoes, including things that I have a difficult time believing are beneficial. How many pairs of shoes do you have in your rotation? How do you deal with scuffs and wear if you are only doing this a couple of times a year as you stated here? If you are honestly walking 20 or 30 miles a day, then that's an unbelievable amount of wear on your dress shoes. Something doesn't add up here.
I know. That happened... Refer to my talk to Pat for references. That shit happened.
I know there are things I did which is difficult to believe, therefore, if you cannot, I would not recommend. It's not like I am the only one doing it - examples of greasing shoes include Benhour, and another SF gents who also did that the other day, although the crazier attempt was with canned mink oil.
Dealing with scuffs was an interesting one. Did you know that Glen's polish can last really long? As in, once I get home, I clean the shoes and all, and with just a drop of water on my brush, I can literally buff the scuffs out, set the shoes to rest, and that was all done. Nothing else was ever done to them. I only give them another coat of polish when they seems to dry or soak up water - and it's Glen's polish.
I know I walked too much in my shoes, but caring and pampering them maybe one thing, but I did not buy them to make them babies in my house. They should be make for walking. A lifespan of 5 years like Pat's? I'll see if it ends there. If it gets beat up in any longer amount of time? Wonderful! If it ends up ruined too early? Too bad. Not made for walking.
As I said, I cannot promise you, but there will be times when I will open a thread, with full pics and writings on how I managed to do it, and you can witness it all for yourself. As of right now, you may keep much of the doubt as you wanted. I already posted pictures of them. Prefer to that.
