Water Spots on my Louvers...WHAT DO I DO!!!

[Ryan King]

Hey Folks.

So unfortunately my car was out in the elements for a few months. (I know I know for shame). I had a car cover on it...but it rained at some point, soaking the car cover, and I didn't realize that water deposits formed on my louvers. I have tried EVERYTHING to get them off. I attempted to use polish to remove them, window cleaner, bar keepers friend, and even tried white vinegar...nothing has worked. I am about ready to repaint the damn thing...but I dont know if that will solve my issue or if they will shine through the paint.

Anyone have any experience or suggestions?

test it at a small spot first, but I'd try some bathroom cleaner that is designed to remove waterspots. CLR or something like that. those are probably mineral deposits. Muriatic acid would clean it too, but I'd water it down a lot and test at an inconspicuous spot.

Try Black Again.

I've been dealing with this as well, but mostly on the the black unpainted portions of the front and rear bumpers. The spots first appeared after it had rained. I first tried wiping them off with a wet towel but didn't help.

Water spots are mostly mineral and contaminant deposits. A dressing will just cover them up or hide them, but not remove the deposits. I would try normal soap and water with a bug pad and some elbow grease. If that doesn't work, Amonia might do the trick, but it may, (doubtful) make the finish uneven, in which it will need to be dressed.

I personally keep the louvers as all black parts dressed and protected. For the louvers I use a different dressing which has a dull to semi-gloss finish which makes them look just like the left the paint booth.

Also remember that some water spots are simply a reaction to the dressing/protectant that is already on the panel or unpainted plastic. I do have to re-treat my chin spoiler after washing as the water dries out the places where it beaded up.

I should add that I have see these "deposits" actually eat into the paint leaving the impression that it's a water spot but in actuality, it's like a bunch of microscopic chips..much like bird crap leaves when it's left on paint too long.

You could try 99% isopropyl too. Should be safe on fibreglass. Try the bottom of the Louvre first.

As mentioned above - Black Again will make many parts of the car look amazing, and for a long time (UV activated). The only issue is if you plan to paint anything you apply it to in the near future. But that will fuse out eventually. If you want a deep black on all car parts, Black Again. Otherwise, there are solutions that will work more naturally - but I was seduced!

Believe it or not, on all the fiberglass/painted surfaces - I use Black Magic Tire Shine, lots of dirt comes off when I use it on the louvers and it stays shiny for weeks - just don't get it on the glass or stainless.
