It's like shoe polish, and a Kiwi cloth in the business world. They're almost necessities. I mean you don't have to go all out and polish your shoes till you can shave using them as a mirror but just wipe the dust off and quickly buff your shoes and you'll be good to go for a business meeting. There are super high gloss shoes that you can buy and that's almost like Green Gas, it has the silicone oil already in it.
Likewise in airsoft, you of *need* it if you're planning to actively game it during the season. Or get the "high gloss shoes" and buy Green Gas.
