Hi guys, I am still learning and I have been using a small mould as a test.  I have just pulled my small money tray made of 2x2 twill carbon out of the mould and there are tiny pinholes on one side of the surface, I am sure that the bag kept full vac all the way through the infusion so my question is what are the main reasons for a pinhole finish. 

I have been working in the garage which is cold but have my mould on an electric blanket to keep it warm.  the only thing different with this infusion is that I didn't use any spray tack on the surface. 

I am quite happy to have these little problems as I want to learn as much as I can but I need to have an understanding of why things happen and how to improve.

Thanks in advance

Thanks guys, its a bit hard to see from the picture as I found it very hard get a good picture of the tiny pinholes on the surface.  I think that the infusion probably went a bit too fast as when I opened the inlet line the pipe was sucked closed and when I squeezed the kink the resin rapidly shot in but seemed like it had good coverage.  I think I will try again this time going really slowly. 

Also I  will be looking into making my own de gassing pot.
