bird poop stained my CF roof

Fast4d · 11-10-2015, 11:29 AM

left two small hazy spots on the CF clear coat.

I tried clay but no luck so it's not on the surface.it has etched into the clear.

what should I use to remove?

my car was 99.99% perfect.

You will have to polish. If you don't have a machine polisher, you can apply some elbow grease and use an applicator. Try and take a pic so people can help assess the poop "damage"

don't worry it will come off!

You should get it looked at by a pro asap. The poop will continue to penetrate until it reaches the carbon fiber. Then it will eat away at the fibers until your roof disintegrates.

I kid I kid.

But from my understanding, the chemical make up of bird poop can't be just "wiped off" if it penetrates the clear. Some abrasion may be needed to get it out. You should probably get it polished sooner than later.

On the bright side, if you car is still 99.99% perfect after this, then it must look brand new. Then I'd say you're not driving your car at all.

I had same issue. 2nd day i had car, and the sun baked it in. I used Menzerna SIP and an orange pad to remove the etched shit stain. For the carbon fiber roof, i usually top every month with Collinite 476. Its not the most "fancy" wax, but if you're familiar with it, it protects extremely well.
