It does promote their product, strictly on the fact that the only way you can use an alu rad, is with their gold plated blocks
, otherwise, galvanic corrosion will take its toll. We've seen it too many times.
There's no glue in a copper rad. Possibly solder (i believe that the cheapest assembly method involves a lead solder "dip").
Their test claims are posted though... "...transfer heat 39-49% more efficiently than a typical claimed "copper core" radiator...".
