Little tip to save so much time and frustration when the ladder clamps get bent is get some threaded bar or studding and bolt it through the roofrack. Then the ladder just goes on the rack and you just spin the top of the clamps on.
interesting...altho spinning the top on and off could be a pain in the rear end too...I might (might) be putting the desmo rack back on, if so the I only need straps to hold the ladder on...much quicker!
ps...are you a secret window cleaner? 
I've personally never found an issue and me and my mate always said it was the best thing ever done on the car.
What's the difference with the Denso rack then?
Yeah mate just sold a huge round. Had a water fed pole set up in the back of the MK4. was awesome. Now just got a small round whoch pays the bills. 4 days a month or 3 long days. Pays car insurance, phone and MOT tax etc.
The thought in the morning of getting up and doing it is so hard but after im out and doing it trad I just crack on.
Flocking looks awesome bud! Is it expensive to have done?
