THANK YOU VERY MUCH FOR ADVISE ONLY NEED TO START FROM SOMEWHERE. SO FROM WHAT MATERIAL IS YOUR MOLDS? also in what temperature it cures? any images of owen so i can have an idea to build as i thought to use piccas owen but its only 1metres on 50cm i need one and good. that be like 2 metres long 50cm high and 1 metre width. 

Use Optimould for your tooling... You also need a tooling gel coat.. 

I will show you what I have done for my ovens when I am using them again... You will need to post cure the moulds. Start at 40 degrees C for a couple of hours and work up to 60 for about 6 hours then up to 80 degrees c for another 6 hours then up to 100 degrees C for 6 to 8 hours. 

Use a chemical mould cleaner then sealer with about 4 to 6 coats of sealer and finally chemical release with another 4 to 6 coats.
