Anyone had any experience doing this? Hints Tips? Good places for a quote and good turnaround?
It's a laborious, mechanical job, as any chemicals may well affect the resin binding the CF.
Are you doing it to repaint, or because you want it 'raw'? If the latter, you may be disappointed, as bare carbon that's not produced to be exposed is not usually the 'weave' that people associate with carbon. It can often look really squiffy and not particularly aesthetically pleasing.
It may well have blobs of filler etc.
You'll also need to re lacquer afterwards to protect it from UV and for a better finish.
If to repaint, then just key it and paint over the top.
Dangerholm always uses a knife for better control, I can see it being a very time consuming process
Selectively strippable technology works for planes. Strips down to a primer. This was an interesting read.
For bikes? Probably just a sand down to lacquer. I did that for some forks where paint was peeling in places. I applied multiple lacquer coats for a decent finish.
Knifed my Scott genius and could honestly have just lacquered it as the layup was faultless.
Just started knifing a yt Tues for a chainstay repair and it's full of filler with layers of carbon that don't meet on the straightest tube. Plan was to knife all then lacquer but I probably won't spend those 20+hours doing it now.
There was a company called carbon strip that made a chemical.
Etoe on YouTube also is using cherry pit blast media and happy to break out the sander.
"Local" U-blast place has a walnut shell cabinet, I might do that just to get the paint mostly off.. but they think it might end up etching the carbon.
Soda blasting?
Stanley blade. and some sort of flat sharpening stone.
Holding the blade directly upright, rub on the stone which removes the sharp edge but creates a burr. It is this burr that makes scraping paint a lot easier.
Hold the blade with both hands, index fingers on the back at the edges, and thumbs in the middle of the front.
Apply gentle pressure to the thumbs to bend the blade ever so slightly.
Then use the burr to scrape the paint.
Its the same idea and process when using a cabinet card scraper, but easier to create the burr because the blade edge is very thin in comparison to a card scraper.
Word of warning. The friction action heats up the blade and can burn your thumbs, so wrap them with elastoplast.
See you tube about using a cabinet scraper for the technique.
