I had been using a mix it yourself from powder solution for tin plating. It’s a PIA and has to be heated prior to use. I heard about Liquid Tin some time ago. Not only do you not have to mix it, you don’t have to heat it. I didn’t bother with it because if it’s not broken, why fix it. Well, two weeks ago, I got aggravated with tin plating so I figured I would give it a shot. I cannot believe how well it works. I feel like an idiot for wasting my time now. I guess I assumed that a solution you heated would work faster and better but I was seriously wrong. Liquid tin works almost instantly and seems much more tolerant of not getting that last spec of oxide off with the scrub pad. I highly recommend it.
