I've been waxing chains for the last year and a half, and then following up with Squirt renewal applications at approx. 10 day intervals, so that I can leave the chain on the bike for its lifetime. It seems to work well. I'm now at the point where I am about to restart the process with a new chain. I do notice that Squirt is not quite as clean as pure molten paraffin applications, and is ever so slightly tacky. Not enough to attract sand and grit, but it isn't quite as perfect as paraffin.
