And I guess by 'best' I mean both longest lasting and best performing? I've tried so many brands/models over the years and it seems that no matter what they cost ($15/blade or $30/blade), or the brand/style/feature/whatever, they all perform about the same which is decent at best, and they don't seem to last very long either before getting squeaky, etc.. I do clean/detail my cars, and pay extra attention to the windshield (so I don't believe there's buildup/residue). I do also live in the northeast so we get all sorts of weather during the year (hot/cold/cold/hot...). Thanks for any thoughts/suggestions.

So my old camaro paint seen better days..I started to sand down the side that the paint was chipping. The car is a darker green I just need some help with what kind of paint I need to buy. I think there is special stuff that I need to get but not sure what. I wanna paint the car black I figure that would be the cheapest and easiest thanks!
