Just for clarification:
It is not recommended to use oil based lubricants (WD-40, GT-85, etc.) on carbon-fibre poles due to the risk of delamination. Whilst this is rare I have known it to happen to a pole's surface when used with these type of products.
The product being talked about in this thread is WD-40 Dry-Film PTFE spray (which is not oil-based) - on my own personal findings when testing this brand it really did not perform as a dry-film PTFE spray should and never seemed to dry properly - for this reason I do not personally recommend this brand of dry-film PTFE spray. It should not cause any specific damage though, but it will be liable to attract dirt and grit due to staying slightly wet and sticky.
