I've been using oil based finishes on my instruments for the past 40 years. It's high time to try out the water based finishes that so many folks are using. I'm wondering what lubricant you all use to wet sand water based finishes. I've always used water with a little detergent mixed in to wet sand oil based finishes, but that doesn't make sense to me when wet sanding water based products. Wouldn't water partially dissolve the finish? Your advice will be most appreciated.
