Sun visor alert
 

Found a seller on eBay with some. I know I’ve seen a few people asking about these before. Not sure of quality or fitment. Obviously they aren’t Lund. Price is right.

Well, that's certainly going to spoil the airflow! :D

Sun visor, yes, but calling that a "spoiler" is just false advertising.

Great price, though.

Those ones from Poland have been on Ebay for quite some time. At least 3 years ago I think I saw them.
Gotta figure somebodies curiosity got the better of them and they ordered it.
But never seen anyone post about it.

Yikes, I get the heebee-jeebees just thinking about poking holes in my roof and pillars like that (not to mention aluminum rivets on steel). They would start to rust in less than 1 season here.

I had one on a 92 S10 Blazer. I was afraid to drill holes so I had the dude I know with a body shop do it. That was like 22 years ago though. I’ve done worse since. It didn’t rust within the 2 years before I totaled it. I also had a ZJ that I put a visor/spoiler on the top of the rear hatch and that was on for quite a few years without rust or leaking issues. I can’t remember if I used silicone or some sort of sealant.

If you treat the holes before you install the fasteners, it shouldn't rust any faster than the rest of the vehicle. Drill your holes, then deburr them thoroughly. Now use a Q-Tip to paint each one with a good quality primer, including getting down inside the cut edge and even slop some on the inside as far as you can. Be generous with it. Let it dry properly, then do the same with a top-coat of a good quality paint that matches (or almost matches) your paint job. Since you aren't spraying, this shouldn't be visible, but it's nice to get it close. A small bottle of touch-up will do.

Best thing is to do the above, then install nutserts. You'll be good for a looong time.

Of course, if you are putting stuff on an off-road junker that's already rusty, just punch your holes, slap on some dielectric grease (Like above 0 get it inside) and install your stuff. A coatingof grease before screwing will do a lot to keep rust at bay.
