Wife's old car is dripping a couple of drops of oil per day. Won't be an easy fix - it wasn't noticed on the old tarmac - but sticks out like a black blob on our new block paving.
I want and easy way of getting my wife to put something fairly unobtrusive in the right place under the car when she parks up. Old door mat being tried - but I get called out to put it "in the right place"
Any innovative ideas?
