hi gents, I have a pair of suede boot that i like and what to give the more rugged oiled suede look like some items i have seen. I have a few questions. 1. can i myself oil down the suede? 2. will it darken the boots and make them water proof? 3. are there any bad reifications for doing so? 4. should i just get a cobbler to do it? the effect i want is a more rugged with the benefits of water proofing.
