Blackness, sorry for keeping you waiting....
I couldn't find the photos I took of the process, so I just quickly ran out, took my rails off, and snapped a few pics so you could see what your dealing with.
The removal of the Black Rubber Moulds;
The Black rubber moulds came off easy enough - I didn't care if they broke during removal. There were 2 parts to the black moulds - the top part broke away first, and then the bottom peeled away from the roof. Do this however you can, just take care not to damage the paintwork on your roof, or the bolts.
This left the remnants of the 3M double sided tape I mentioned before. To remove this, I used a plastic scraper (to not damage the paintwork), a product called 'De-Solve-it' (from bunnings) and a cloth. This part took the longest, cause I wanted it to look good & clean. You can see parts of the 3M tape I left in this pic between the bolts, because it would have been 'out of sight'.
Installation of the OEM Production Rails;
This was VERY easy. The rails came assembled, with nuts to fit on the bolts already located in the roof of the car. Just make sure you sort out which rail goes on which side, then place them over the bolts, and tighten. Finish by placing the covers over them and VIOLA! The car now has roof rails!
Again, I hoped this helps.
