so I made a halo 5 recruit helmet about 2 years ago... I wanted to finish it. procrastination am I right? it was the first project I ever did and it was pretty rough, but not bad. pretty good actually, just had some holes and not flat-ly ideal spots. I was putting down clay but that was taking Way to long and on top of that I would have to sand it. I asked my family what to do and I was asked if there was anything I could dip it in to give it a coat of something that would dry out hard, fill in all my holes and gaps, and I could sand down. I didn't think it would work but now that I went over it, it sounds like a good idea. does anyone know of something I could use? hopefully cheap and convenient? thanks
