So what you meant to say, actually, is that Carl liked a number of products, two of which were Shell and Penrite.
*sigh*
As usual, your initial post was ambiguous and misleading.
Thanks for finally manning up with the clarification.
Like I said, well done on the change to Penrite. You should have taken Carl's advice about it years ago. You know how he researches his stuff!!
