Wet n dry and patience ?

they come painted from the factory , also it looks like powder coating as on the one i ruined had lots of layers.
underneath is nice carbon fibre so i dont know why they covered it.
I tryed wet n dry in an area and within 5 mins i had not even got down to the carbon , the only thing it removed was the skin of my thumb.
here is a pic

What about doing a single color powdercoat over the graphics instead?

I think W D Pro has got it right here, plenty of elbow grease, patience and wet and dry. Don't use chemicals as it can affect the bonding of the fibres. :shock:

I don't think carbon fibre can be powder coated. Powder coating is usually applied electrostatically to metal, I'm not sure if that can be done to CF. :?

I used nitromors on this - it came up pretty good. Hard scrubbing also with a sanding pad.

You really should not use nitromors on it as the solvents attack the resin. While you can often get away with it if you are quick, it is still attacking the resin matrix and weakening it.

The best is a glassfibre paint stripper - usually marine suppliers carry it. This is less aggressive on the matrix.

If you intend to show off the carbon, you MUST clearcoat it with a UV-resistant varnish. Sunlight otherwise will attack the matrix, which will weaken it severely and also cause it eventually to go milky.

A marine 2-pack varnish such as SP Systems Ultravar is the best way to finish it. Beware though, this needs specialist handling. It's not cheap either at £80 for 1.5 litres.

The Scott above isnt really carbon - its more like plastic canoe material like the Trimble - "Thermoplastic"

Hmmm, dangerous game. Usual advice about "try on a small area" applies :?

I have stripped glassfibre with Nitromors (boats) but you have to be very, very attentive.
