I personally think the sport is being neglected by all the aftermarket companies. I see Bronco sports on the road every week and only 3 full size Broncos going down the highway in the last 6 months. IM JUST SAYING! Aftermarket companies need to get on the ball. There missing out on a lot of cash.
I'm currently looking at vent shades. I'm Undecided if I'm going with the Ford shades or AVS. Both have low profile. I've had AVS on my 2011 F150 10 years and never had an issue with them.
You should not clean it off. It there to help protect the terminals. I just had the dealer install a new battery on my F150 and told them to put an anti corrosion grease on the terminals. That is the correct color.
