Now that ^^^^^ does look good!
I've finally, after all sorts of delays, got around to claying my GTI and giving it a decent coat of wax.
I used my new Wo-Wo clay mitt, which worked very well, using a Quick Detailer as a lubricant, and used DoDo Juice Super Hybrid wax. Quite a lot of work, but well worth the effort. I'll repeat the exercise in the Autumn, as preparation for winter. Tomorrow I'm hoping to finish off by waxing the wheels with Poorboys Wheel Wax, giving the tyres a wipe over with Gtechniq Tyre and Trim, and using Auto Finesse Dressle on the rest of the trim.
