So I had a bottle of "wax as you dry" and after I washed the Z I could not get the sprayer to work so I broke the bottle as it was 1/2 empty and splashed the contents on top and around the car to see that there were these chunks of wax all over and well they got in every little cranny there was later to have it roll of on to the car after I dried it...just got in and fixed it with a nice coat of Zymol....love how small this car is and I can actually reach from one side to the other without touching the sides with my sweaty arse...
