carbon fiber trunk badly oxidized on edges tried many options

Hey guys,

I just got a used VIS hood and I cannot remove this oxidation shown in the pictures for anything. I have researched and tried all the methods posted on multiple forums.

Using the 3m marine coupond for fiberglass was very popular and worked wonders on hazing hoods, but mine seems to be a lot more concentrated and thick in certain areas instead of light hazing. It did not make any change in mine.

More info after pics





I also tried the wetsanding method with I was able only to get the yellow discoloration off and ended up with a clear-ish white color. I was not willing to wet sand anymore being that I did not want go through the gel coating and ruin the trunk (I had been successful removing the oxidation on a specific bad spot for a long time the night prior wetsanding like crazy on the same spot until it was practially gone but noticed I was down to bare carbon fiber.

I have yet to bring the hood to a shop to see if they can get the oxidation of with a buffer and compound or remove the oxidation and clear coat it. Is it worth the money/risk of more damage? Just wanted to know if anyone else has experience with this that may be able to help me.

I purchased this hood from a reputable guy on ebay who had 100% positive feedback and a lot of transactions. He mentioned it was in excellent condition and did not mention the oxidation at all. I took his word for the condition. (I have done business on ebay for years with only good experiences).

He did refund a fair portion of the purchase cost after I contacted him and mentioned Integrity. I paid 215$ after the refund for it plus 150$ in shipping total -365$

I'd say your best bet is take it to a good bodyshop and see if there's anything they can do but the only way to get it looking good again might be to paint it.

possibly a good wetsand and clearcoat might get it back. it looks pretty far gone though.

Re: carbon fiber trunk badly oxidized on edges tried many options

It's a bit hard to tell from the pics but it looks like the resin on the edges is too thick and has discoloured. Unfortunately, no amount of sanding or polishing can fix this.

If you want to keep the carbon look, the best thing you can do is lightly spray the edges with black paint that feathers out about an inch in from the edge. To keep the hood looking good for longer get it coated in a quality UV block clear-coat.

Re: carbon fiber trunk badly oxidized on edges tried many options

Great answers everyone. Ausluder you are absolutely correct. The oxidation is so consentrated and discolored that it goes all the way through the gel coating to the carbon fiber itself.

I know that for sure as I sanded it all the way down in a spot until I removed the discoloration and I could touch bare carbon fiber. I took it to like 6 shops yesterday, most didn't want to touch it.

I came up with a plan B to do exactly what ausluder said. Spray the edges with black paint evenly to cover the discoloration, then clear it on top of that. It will look better than it did brand new. I will post pics when I get it back.

Thanks guys

Re: carbon fiber trunk badly oxidized on edges tried many options

Sorry for the crappy pictures, I used my phone in my garage with poor lighting. I'm sure you get the idea. Looks better than it did. When you look at the entire trunk it looks like it came that way brand new. Definitely the clear coat brought the carbon fiber back to life.

Re: carbon fiber trunk badly oxidized on edges tried many options

Tried to get as many angles as I could. All in all, I think it looks great compared to what it did look like. The clear coat looks awesome and it will keep it protected well. Honda4lifeprelude, I do like that idea. What I have learned over the summer is you never know how something will look until it is on the car. It would probably look tight though. I wanted everything to flow just right. The roof is wrapped in 3m di noc carbon fiber with a bit of clear coat to shine it up, and my BRAND NEW cf hood should be arriving shortly. What do you think about having the hood outlined the same way to match the trunk?
