Hello again Wonderboy,
Like I said in your other thread, I've used it successfully and I'm happy with the product. I'm not a company shill or anything, just a customer.
You'll want to know that apparently in the States there is a bit of a controversy as to the safety of using a hydrocarbon based refrigerant in an automotive air conditioning system. Personally I believe its all hype by refrigerant industry folks worried about their jobs/market share etc. But its up to you to decide.
Here's some links for and against:
