I understand reviving an old thread with a non-bike application. In this day and age, it is hard to start a thread on a bike forum that is not bicycle related without getting flamed.

That said, acetone is pretty nasty and I’ve used it on polyester surfboards without adverse effects, but I wouldn’t soak it.

I’ve also used carbon fiber cloth with polyester resin. I believe it is the bonding vehicle, resin/epoxy, that gets impacted.

As for epoxy, I’m not sure if the variables used in bikes vs marine, but I would think getting info on West System epoxy might help.

I’m positive there are others who can offer better/correct info than I can.
