Re: will Stickers/Decals on the front windshield damage windshield wipers??
over time and use of wipers, the stickers will be scuffed up, begin to peel back/off, and probably cut/mess up/wear out the wiper blade as well as the wiper is designed to remove water from a "smooth surface" w/o the leading edges of the stickers, no biggie, but don't expect either to last a long time.
Life is not a box of chocolates. It's more like a jar of jalapenos, what you do today may burn you tomorrow.
