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.

My question is, can i use a filler to smooth the whole plug over and fill in some of my voids?Blink If yes what type of fillers? should i use Bondo which i've been seeing is "acceptable"?  Blink

If i use Bondo to smooth the piece, do i need to put resin back over it? Or, do i just primer over the filler and polish and sand that smooth to then start on making my mold.

I want this to be perfect and not have wasted a few months of work trying to learn everything I have. Any information AT ALLLL is greatly appreciates. I'm new to the fiberglass world and from what i've seen with forums this seems to have some good help and creative people.

Thought i'd give an update, i finally put on my few coats of filler, making it stick to the fins is deffinetley a project, i may end up sanding it down and coating again. Either way, I am trying my best to get it as smooth as i can. Is the 2K primer going to smooth out the filler in the monor imperfections or is the point of the 2 k just to seal my smooth filler. Its proving a task to get my curvature smoothed out. 

Any help i give my thanks in advanced!! so far you all have been more then helpful. Appreciate it, and so dosent my car.
