Wax on rubber and plastic....Rain or bird crap right after you wash the car (paid to get the car washed this week..not only did it rain the next day, but about 15 birds had a party over my car! and after I got it all off, they got me again this morning..and AGAIN this afternoon!!!!
)
But the biggest pain in the butt is the windshield and rear window. I can get them good and clean, but I'm hurting pretty bad the next day. Plus, I always find little armor all smudges around the edge of the windshield. If only it was an easier spot to get into...
