2006 paint color guide :
There were no iSonic 133 available in Technora either in 2008 or 2007, however :
The iSonics only available in Technora in 2007 were the 145 and 155: http://2007.star-board.com/viewpage.php?page_id=31
An iSonic 135 was available in DRAM in 2006 : http://2006.star-board.com/products/isonic.asp
I bet you've got the 2006 DRAM iSonic 135 and the black marks being revealed under the paint finish are not carbon layer but Dyneema fabric being exposed from the DRAM layer.
