There's nothing wrong with asking any body questions, it how we learn. Although for me, noob or vet, asking questions to which the answer is so easily found can frustrate people some times so like I state on my foam info post read, read and read some more. If the answer doesn't reveal it's self then ask away or you'll never know the answer
If you ever find your self stuck and don't want to bother what you call a vet, we are all noobs in my eyes as there is always something to learn, then send me a PM as I am always happy to help where I can as I know the guys here will be too. This is a great community and from my personal experience every body here is always happy to help.
As you are taking the pep route I would highly recommend checking Cerealkilller and Sara's threads as their work is outstanding and have good wip pics to use as reference. Cereal has some of the best tutorials out there in the video section, they are well worth watching. I have taken the foam route and still I have watched all his tutorials. In fact they are so informative that I think once my Ironman helmet is done I will try at a PEPed helmet next.
One thing I would recommend is make a pep piece, scaled right of course. Then take it to the finished product. I started a PEPed ironman suit and then found I wasn't so good at the bondo stage (well wasn't using quite the right products). So wasted a huge amount of time cutting and sticking together the entire suit. It turned out foam was my thing. Once you have made one piece then you know you have what it takes and would have learned the skills and techniques to apply to the rest of your suit.
Well I wish you well and like I said don't hesitate to ask us anything but make sure you do as much research as possible to insure you reach your goals
Tom.
