Very easy to clay the car, took me about an hour I guess. Best method I found is to use some cheap car shampoo (I've got a gallon drum of turtle wax), make it really really strong in a bucket (about half an inch of shampoo in bottom of bucket), then use a bottle or something, fill from bucket, then keep paintwork really wet and soapy as you use the clay on it.

Black headlights are on the list, but can't get these ones apart to paint so would need to buy replacements, and they aren't cheap!!!
