Sorry Ed, been super busy last few weeks, with no end in sight till end of June... you know how it is <img src="/forums/images/graemlins/wink.gif" alt="" />

I had my ac system topped up with said stuff last summer - its been awesome. Many imports I've seen come in have had empty systems that worked when topped up - kinda makes you think, doesn't it? <img src="/forums/images/graemlins/ignore.gif" alt="" /> Anyways, its worked like a charm ever since... kinda tricky to find the port, but its down there - strong flashlight helped...
