I just got a quote for flocking my Dash, Door Cards and Center Console from www.Autoflock.co.uk and i was actually suprised at the price to be honest... £305 inc collection and delivery which i thought was pretty good considering the size of the items. All work is warrantied and all work is documented and accompanied with a photo diary of the work being done..
I am in no way affiliated with them but thought it was a very good deal.
