Next step...
I reapplied the face of the helmet and used "For sale" signs to add 1 1/4" shims to get it back to the proper length. I also used the same "For Sale" sign to build the cheeks. At this point, everything is loosely held in place with hot glue.
Time: 30 mins
Cost: 1.00 (for "For Sale" sign)
Total time: 1 hr 30mn
Total cost:
Actual: 36.00
Estimated: 53.00

The added length on the face exterior was covered with 2 part plumbing epoxy. I prefer this as it has a clay or putty like consistency, until it sets then it's hard as a rock, so when applied it can be sculpted to shape without it oozing out of shape. I had this epoxy on hand from a variety of projects however, to buy a new tube it's about 4.00
Final step
before fiberglassing the interior of the rebuilt face of the helmet was to cover the exposed electronics fron where the face was removed. I used scrap from teh same piece of "For Sale" sign I used to rebuild the face of the helmet so there is no added cost. Again, held in place with hot glue.

On to the next...
Helmet rough sanded, just a little cleaned up, for Bondo application. Anchor holes drilled into the dent. For those unaware, the anchor holes allow a small ammount of Bondo to seap through where it can be smoothed on the interior. This allows an anchor for the Bondo glob that helps prevent it from popping out.
Time: 15 min
Cost: 0.00
Next, Bondo is applied along all the major seams to be filled. Again, with this build I am leaving the vents in the back of the helmet open for airflow and I am keeping the electronics functional so you may still see the buttons on the earcap. Don't worry, that will be addressed when the time comes.
I had the Bondo on hand so again, no cost out of pocket for this project. However, if you don't have Bondo on hand and have to get it, it's about 8.00 for the small can.

Glazing Putty applied and sanded. this took 2 cracks at it to get it smooth enough for the next step. For those unfamiliar with Glazing Putty, it is a product made by Bondo that you do not mix. It air drives. Where as Bondo is a large area filler, Glazing Putty is for back filling shallow small imperfections. If you try to put it on too heavy it will crack and fall out. Now, I have a coiuple of tubes on Glazing Putty on hand. So again, no additional expense to me for the build. However, if you have to purchase it, it's about 4.00 a tube.
