Carbolift didn't work at all for me. Seeing as you will have to sand it down afterwards, I would not use it. Go for the razor blade method and finish with fine grid paper (1000 and upwards).
Removing a color paint job will save you some 50-75 grams at best. Removing a clear coat will save you a lot less. Also take in account that Cervelo will have used only a tiny amount of paint to achieve a low weight AND that you will have to clear coat it again after you have removed the original paint. As such I would either leave it bare carbon (UV won't degrade it overnight, more likely in 20 years or so) or leave it as it is.
Thanks and you have help make my decision easier as it seems like a lot of hard work for very little if any reward.
