For us newcomers that doesn't have all the equipment in the world.
How do you go about sealing a fairly complicated 3D printed plug, to make a mold for resin infusion.
I am looking to use the uni-mold system but I don't have the equipment to use a spray gun and 2k primer to seal the 3D printed mold
Would it be possible to sand out the print lines of the plug and go up to something like 800-1200 grit and then do the final polish on gelcoat of the finished mold?
But how do I go about not having the plastic plug sticking to the mold?
Is easy lease enough? Maybe some wax and PVA? Will some kind do release tape work (complex shape though)? Seal the plug in epoxy? What about printing in dissolvable plastics HIPS + D-limonene, PVA and water? Print in PLA heat up finished mold in water bath or oven to 60-70C and peel the PLA from the mold? Or just say f*** it and sand the plastic down?

Thanks a lot for the reply Hanaldo and Warren!!
Sorry for late response
What are you guys opinion on envelop baging, vs regular flange baging, vs silicone bag. to make anything from 20-100 parts in the same mold. and what release agent would you use for that kind of numbers.
Is it possible to make a silicone bag on a existing mold made from the unimold system if I ever get tired of the baging process down the road?
And what would be your weapon on choice to cut a lot of carbon cloth for infusion? needs to be exact up to +- 1 cm. Thin plywood template and pizza wheel? scissors? or something else fancier?
