Is there any way to protect the wiper blade arms (the part that is actually attached to the car and not the actual blade nor blade holders that you replace) from oxidation? I just know in time that the flat black paint will begin to fade and eventually flake off in the Florida heat and acid rain. My wife's Accord which we had for 6 years had this problem where you could see the raw metal underneath the faded and flaked off black paint.

I used a little car wax on a small spot to see if it comes off easy. And it does but I'm afraid the wax will accumulate in time and eventually turn the black to like a gray...or something abnormal like that. Also I don't think that car wax is meant for that type of flat finish.

Any thoughts of what I can apply or do to prevent this?

Meguair's Pro Series Tire & Trim Dressing Gel works very well on things like windshield wipers. It is also excellent on the rubber/vinyl trim - will bring "chalky" grey trim back to black. It goes on easy and buffs nice.

Just be sure to do this before washing/waxing your car, as I have always managed to get a bit of it on the car, and it leaves a greasy residue = extra work to buff out the greasy spots on car body!

Any Meguiars stuff that says it's for this will work brilliantly.

What you could do aswell is remove the whole assembly and spray laquer on the part in question. It'll bring it up beautifully and will last for years. The surface is rough enough to hold the laquer too so it won't run considering you spray a thin coat each time.

agree with whats been said as you will be doing trim work anyway. BUT in case you forget the blade arms or something, just take em off, sand em very lightly with 800grit or so depending on condition, and respray them with gloss black trim paint. takes 15 minutes plus drying time, costs about $5, and its easy

What about Aerospace 303 Protectant? That should work fine. It works great on tires, weather stripping, and wheel wells. I think I heard people said it worked fine on wipers. I haven't tried it myself before though.

Repaint the damn things with Rustoleum.
