I've used Windex before to find holes. So it should work.^yes i was going to bring the baldies to your attention. Good job on the plug. I've never done one yet. I should keep a plug kit in the car and some soapy stuff. Does glass cleaner foam up as good as all-purpose cleaner? And i keep windshield washer fluid in the hatch, will that bubble up too?
If there's a macro setting on your camera, that will help with the close-ups. Good write up!
