HAFC

Unless HAFC can be verified by a legitimate independent testing agency, it's moot. If this product works as well as advertised that should be easy to do. In fact, I would think Dennis Lee would call a press conference to demonstrate such and end all doubt as every car owner on the planet would want one.

If and when independent verification is established, then HAFC discussions can continue here. Otherwise all posts on this topic will be closed and/or deleted.
