Carbon Fiber Roof Saved! dreadful gel-coat fix

[jvictormp]

Well, I decided to re-sand with 600 grit to avoid addhesion failure of clear coat.

First hand was good, in my opinion.

Second hand, I increased the area, to try to "blend". But I made the mistake of reducing the flow, so it got that dusty appearence. (there is no picture of the second hand, goes straight to third hand).

Third hand, increased the area again and finished the job.

Next step is sanding: 1200, 2000, 3000, then polishing.

I am going through this right now with my 2015. I took it to a body shop and the owner told me I should try to get BMW to warranty it because it should not do what it is doing. There was no reason it should start to delaminate. BMW quoted $14.8k to replace the roof and would only cover 1/2 the cost in "good faith". The body shop wants $3400 to strip and clear.

I am looking at a 2015 out in Santa Monica CA that has some spots on the roof that are starting to peel. What have some of you other guys paid to have the roof gel removed re-cleared? Also, any recommended shops out in that area or near Washington DC to have it done?

Thanks!

I noticed that a few people in the Bay Area have had this work done or have done it themselves.

Any good recommendations in NorCal?

sh*t I forgot to return after concluding the job.

turned out pretty good for the effort and cost. and it's been three years without any signs of "ressurrection" of the initial wear.

So I myself have done countless hours of research trying to figure out who else saved their carbon fiber roof from the peeling gel-coat. The most i found was one guy with an M6 made a video talking about his roof and ended up painting it the same color as the car. Well folks, that does not satisfy me. I purchased the car for the car and its performance and aesthetics. Painting over the looks of the carbon the same color of the car would be nothing but an utter disappointment. So here I am now writing up on this experience and hoping i give a deep insight on my experience on recovering the roof without sacrifice. I am also conducting this write up to help give people the relief that they to can also salvage their roof from the horrifying gel-coat that becomes weaker over time from outside sittings. Not only have i taken plenty of pictures but i also made some video footage of my process for them DIY guys. I want to make this write up simple and fast because no one wants to read forever. haha.




Lets begin



remove the antenna cover, it is double back taped so you can get some sort of strong thin plastic to removed it cutting through the tape. once removed, use a T25 or T30 torque socket and pop the antenna off. I suggest taking a picture of the wiring plugs to ensure its plugged back into the same slots.

Peel from the beginning center of the roof

Work your way around until entire center is peeled

in my experience the 4 corners begin to become a challenge. that is because [...]

Hello there, I am not able to do such great fix. By any chance do you know what would be the cost for body shops to fix it?

The price to repair an E92 M3 carbon roof will depend upon your zip code i.e. the cost of local shop labor and materials. Expect to pay approximately between $1600 to $2300. Here's a few more threads on the topic.
