Ok my friend , ill give it a shot makes sense.....cheers

So a single layer of Easy Preg surface layer with no backing?  If so you may find that is causing your problem.  I've tried knocking up single layer parts and it seems there isn't quite enough resin so you get either pinholes or it looks like the resin surface layer seperates from the carbon slightly.  Add the backing layer and there seems to be enough resin to stop this happening.

Hi Warren I'm the chap that went outside to look at your bonnet on your car in the car park if you can remember. ..... anyways as you can see the predicament I'm in with my recent post"...The pre preg I'm useing is the easypreg surface layer..." please mate with your wealth of knowledge could you advise

You don't mention which pre-preg you are using our Easy-Preg Surface layer or normal Vari-preg?

With normal pre-preg it is very hard to get a very good cosmetic finish out of autoclave.

When using prepreg you typically use a non perforated release film so it doesn't bleed the resin out of the fabric.

Thanks my friend for advice, yes I'm going to try putting it back up to the ten hours but slow the whole ramp time down and even it out amongst the ten hours ....thanks

Hi my friend thanks for your reply it is very welcome , I'm going to try and control the ramping via a pid temperature controler' when ive figured out to use it...lol but as for your other advice about the vacume and degassing solvents" I do fortunetly have full vacume all through the cure process but I'm not sure what u mean about the solvents,  anymore info would be appreciated. ...

Hi this is the sursurface of the the mold which  is constructed useing the uni mold system and seems to have a a good finish , I also had thoughts that because having full vacume all way through the curing cycle that the vacume could be pulling the resin off the part before being able to set....?

Hi my friend thankyou for your reply which is very welcome ,

as above, are you leaving your vacuum on?
