I just purchased a Speedy 30. The handles had a spot on them, so the owner used the MC eraser on them. This dried the handles, so she then used lotion on them. This in turn darkened the handles a bit. Now, my question for you is, in order to get a patina, should I use anything else on it? The patina can get darker, but should I spray it with a gaurd for rain, or condition it with anything? Here's a picture: Thanks!!
