Dovo makes a good razor, a real razor unlike the Kreigar. You should be fine with that one or similar. As for lather, no it can't be saved.

If you're looking for shaving and stropping videos, just use the Search tool in the upper right corner of the page. AFDavis11 has a good one. As for the rest, I think you left out after-shaves and astringents. You can find them on Amazon, etc.

As for spraying your strop. Don't! Regularly warming up the strop by rubbing it with the palm of your hand is all that's needed to keep the strop in good working condition. That was a tip I picked up from Gssixgun.

Cheers!
