If you offered your standard prepreg backing layer with the 'surface layer film' on top it would be perfect.  A very resin rich (even if not the perfect ratio) would solve all my layup issues.  Essentially taking your backing layers and adding the film making it a double rich layer.  This would solve the pinhole problem, the stray fiber problem, and the wet sanding allowance problem.  

No this is another material supplied by SHD.. I tried it a year ago when I first started and it was full of pin holes but was nice and clear just a shame about all the pin holes... But a year later and a few parts made since I started I have learned quite a lot, even though I still have a LONG way to go before I am happy. (you always keep learning more so that never stops but I still feel I have a lot to learn before I can be confident that I can take on customer work and be happy)

It is harder to get a good surface compared to easypreg/ VTF261 but it can be done... The material the original poster is using is the easiest to use of all the Out of Autoclave materials.. If you cannot get perfect parts with that you would struggle with any other material.. But it is about getting everything just right... The material he is using does not need changing to improve its finish and ALL of the other manufacturers have been trying to copy it for years and none have got it right. The down side is you either pay Easy Composites prices or IF you want to buy direct you have to now buy 50sq/m of the material as a minimum order.. That is why I have been testing other materials and all of them need different lay ups and breather stacks and/or cooked differently ect.. So there is no one way that works for every material... Again Tom another reason someone showing you how it is done may not work if you change anything or have to use a different materiale ect.. Even how the oven works and how fast it heats up will make a difference.. So one oven my be perfect but use another without knowing the different way it works may leave you with parts that do not look right...  My first attempt was not good but this one is perfect... It is due to more experience and knowing my box oven will work how it needs to for the material to flow and then cure at the correct rate.
