Hey guys, my first razor and strop is arriving later this week. I didn't buy a brush, soap, or cup because I'm leaving town for two weeks. I couldn't find a good answer online so here goes.

I am curious if one could shave with just water applied to the shaving area. I don't have a thick beard or thick hairs, just a mustache with medium thickness whiskers. Is this possible for touch-ups and trimming?

If this is ill-advised (to which I wouldn't be surprised), can "canned goo", like gillette gel or barbasol, suffice?

I promise to buy a shaving kit when I get back from Vancouver, lol, but I reaaally want to try out my first razor.

Thanks guys!
