That's really just personal preferance. You can spot putty the holes if you want but you don't necessarily have to. When you resin the outside of the helmet be mindful of the amount of resin you're using on or around the holes and when you're done with that particular area, flip the helm over...
So if it does fit too snug, how do make adjustments before resining? And for that matter, I'm kind of a tall guy...6'4" to be exact, so how do you make the adjustments for the rest of the armor? Or are there seperate prgrams of pep for us taller people?
