I have managed to get good results with the XT135, but I did find it critical that the material is very very fresh. Even a couple of days out of the freezer will lead to pinholes. I didn't realise you have to use perf on this material, I haven't used it before but it's similar to another preg I've used from SHD. Everyday is a school day.

I've just re-read this, did you definitely use perforated release film? If so use solid release film next time as you will be drawing resin out of the part!

Thanks for your reply's. Makes seance that it has expired, I have had it for 5 months in and out the freezer it worker perfectly up until the 3 month mark when cavities started forming on the surface...

If it works, there's no real problem doing it. The tooling pre-pregs will have a tougher surface and so the mouds will last longer, but if you're only doing a few parts then it will be fine.
