The problem with just gelcoating your would have to brush in a significant amount to acheive a thickness without using the matting. The matting once wet with fiberglass resin isnt thick at all and helps hold the resin together. If you just brush in a thin layer of gelcoat with no mat then Im afraid it will be to brittle. If you brush in to much then your gonna lose the space you need. I would brush in a thin layer of fiberglass resin and lay in one layer of matting in. Youll get the stiffness you need without compromising head room ...one layer of matting is going to be roughly the thickness of a few sheets of paper.
I think the problem you had with my helmet you got was because of the mods made the rounder dome and the wider flair it took away that little bit of extra space you needed to be comfy from your nose to the back of your head.
A standard dp helmet is gonna give you a little more front to back room as the helmets in their original shape are a little narrower and dont have as much flair as the one you got from me.
Also you dont nessecarily need to do the whole interior of the helmet with fg just the more problematic areas like the lower back area and the lower cheek panels. Reinforcing just these areas will result in minimal loss of space.
As far as the smell of fg it does stink but cures quick enough where you can just do it in front of a fan that is exhausting out the window. Geltime depending on room temp. is usually about 10 minutes. The more catalyst used will speed up the process but i dont recommend over doing the catalyst as if it cures to fast you may get some cracking of the fg because of the heat generated during the curing process. If your room temp is between 60-80 degrees youll acheive a gel time in about 10 minutes the cooler the room the longer it will take but not by much.
You can buy a quart of fiberglass resin and a yard of matting at your local automotive store for about $10-$15 for both products..the catalyst comes with the resin and just follow the direction on the can.
I also recommend buying "acid" brushes to do it with these can also be picked up at the parts store usually about a 1.00 for a dozen. If you need anymore info on how to do this lmk ill make my number available to you.-Jason
