UPDATE!! Due to airpockets i ran across, i redid my helmet with FS's model andthis time used Shell Shock by Smooth-On. Heres the progress so far.
Cardstock helmet, made to the default scale. Barely fits on my head, but once its on i have plenty of room.
First i put on a good coat of primer, Duplicolor High Build formula. This was just to make the paper a bit stiffer and less likely to shift when the urethane plastic is brushed in. Plus it filled some of the smaller gaps in the paper.
Heres the Shell Shock Slow, parts A and B and the instructions/MSDS (Material Safety Data Sheet). ALWAYS read the MSDS before using any type of composite etc. And ALWAYS use a respirator.
Heres the mixing containers i use, you can get them in the painting section at Wal-Mart, Lowes etc. The mixing instructions say to stir the jar of Part B before mixing so i did that being sure to scrape the sides and bottom. The mixing ratio is one part A to four parts B, so i filled the container to the 4 ounce line with Part B and used a smaller measuring cup to measure out 1 ounce of Part A. Then mixed Part A into the container for one minute. The instructions said it would begin to thicken immediately, but i didnt seem to notice until about halfway through the batch.
And here it is brushed into the paper helmet. i was afraid it might come out through the gaps in the paper, but it didnt seem to leak at all. The Slow formula has an 8 minute pot life, but i still had a tiny bit of waste when it got really thick and i couldnt get it out of the mixing container.
All in all i really like the Shell Shock, depending on the final results, i may use this in all of my helmets from now on. My plan is to sand as little of the paper as possible. Once its done im going to give it a few more coats of primer and try using some spot putty to see if thatll fill it in enough.
WETA ODST or Tre Battle's Marine helmet is next.
using all Smooth-On products, seeing as how theyre located in Easton, PA which is 1-2 hours from my house. I ordered this on Friday afternoon and got it on Tuesday. The tracking said it shipped Monday, so if i order on a regular buisness day, ill receive it the next day.
anyone with experience molding please shed some light on this. i have a general idea but theres no such thing as too much knowledge.
