Does your patina still get that nice shine/sheen if you spray it with a water guard such as Kiwi/AG/SM? Or does it patina without the shine? Does your vachetta look dry as a result of waterproofing?
What did you spray yours with? I used Kiwi Protect-All. Yes, it does feel slightly different (I thought it was my imagination). No big deal, but it kinda feels slightly more rigid.
