Hello everyone, my name is Alex,  i am a newbie to this mold and plug making game. Its been brain aching looking at all of these chemicals and processes that i feel everyone has and does differently. I have a MKV VW R32 and i am taking the plane jane exhaust surround and making it DTM styled. I've already added the fins and coated the whole unit in fiberglass. The product is smoothed over and i'm looking for assistance in my next step. I want to make a mould of this unit and that i can use to make a few one off carbon fiber duplicates. I will be honest i have a few bubbles from the fiberglassing and they need correcting.

Hi Alex and welcome. Nice car by the way You haven't said how you intend to make the carbon parts ie wet-lay, infusion, vac bagged. This will make a difference to how and what the mould is made from. Without stating the obvious the finished part will only be as good as the mould so spend the time getting your pattern/plug perfect. Standard body filler is fine but it will need sealing with a 2k based paint. I prefer 2K high build primer, this can be flatted and polished to a high gloss. You also need to pay attention to any undercuts that could cause mechanical lock and prevent the mould releasing from the pattern. I would put a slight taper on those fins you have added as these could be a potential lock area. Also depending on the rest of the shape you may need a multiple piece mould. Quite ambitious for you first go so good luck
Any more questions just ask, there are plenty of helpful people on here.
