Wrong, fast curing resins are a pita, you want all the control you can have to lay up your part and have it cure when you want. Ideally you want a resin that won't even start curing until you ramp up the heat. Curing too soon (rsult of short pot life) will ensure bubbles and porosity just like your rear sets
you need to make sure that all the bubbles are gone and you have intimate contact so that there are no voids for large bubbles to form becuse they will collect there...
ya hahah zip lock... good idea genius....
Taking short cuts will see to haveing crap for parts and dissapointment every time you demold... don't skimp and use the propper materials, a well perforated release film will do you well
Here is a list of materials you will need starting form the mold and working upward.
mold>carbon/reinforecment>release/peel ply>perf. film>bleeder and breathers positioned depending on how much excess resin you are trying to get rid of
keep in mind that too much resin means that you will have to bleed out a lot....and chances are that it won't all bleed out and your parts will still be resin rich. When laying up make sure to only use as much resin as necessary to wet out, try and aviod the temptation to lather it on there excessively.
I'll post back whenever I can, I'm pretty busy right now.
