If it ain't broke, don't try to fix it.

CF is used a great deal now in the building of high performance boats, because of it's very light weight to strength ratio, and is laid up using resins that are ordinarily used with fiberglass. There is oil and gasoline prevalent in the fuel cell area of these boats. And, the problem you mentioned is not a problem with the CF, but with the resin itself used to lay it up, right? So, how can the problem be with the CF? Anything, when used in conjunction with an inappropriate partner material, can fail. That is not the fault of the material itself, but rather the procedure and other materials used.

Which resins exactly are the problem ones?

Wikipedia wont help that much because a lot of the Carbon fibre sheet is pre impregnated with the resin and just requires heat and pressure to make the bond. Though you will find that the resin used is part of the manufacturing process and therefore cloaked in manufacturers non disclosure.
All that said the longest length of metal I have ever put in the wrist of a gun stock is six inches by 10mm (three eighths of an inch diameter). Though it was not a solid piece of Marine grade 316 stainless steel rod I put a 6mm hole through making a tube to reduce the weigh and still giving enough support for the break because Marine grade stainless is dam tough. So carbon fibre rod held no interest because I doubt that there was much different in weight but a good difference in cost, also as I said stainless is far less reactive.

Amen to what Craig said. I have a hammer gun that was completely broken through at the wrist. No idea who or when it was repaired but it has since shot a lot of shells and has held together perfectly. Just shoot it and don’t worry. Now, if you’re considering buying it you have a powerful negotiating point on your side.
