Hi Pete, yes, I've put a bow across my Presto lights. I followed their instructions to sand and resin, and it worked well enough. I had a one-off dep in a military band and it coped with that fine without needing a string change.
I also have an email from Jonas at Lando Music telling me that it's OK to use alcohol to clean off the rosin afterwards, but warning me not to get it on the instrument because it dissolves spirit varnish. I didn't have the heart to tell him it's only a plywood factory bass which was probably sprayed with celllulose!
