I wanted to share a little anecdote about Redline and how they listen to their customers. A few years ago I complained to Redline that the neck on the bottle of Sl-1 was too thick and consequently would not go down far enough to depress the misfuelling flap on my gas tank. Within a couple of days I got an email from RL saying they redesigned the bottle with a thinner neck and asked me to try it out. They sent the bottle along with a "S" shaped funnel.
A++ customer service from them.
