Failure Is Not An Option
As I’m building up more layers of glazing putty, I’m noticing that it tends to just fall off of the vinyl. It’s not adhering very well. This is not good. So, rather than take the chance of it failing after the entire helmet is completed, I’m going to attempt a different route. The fiberglass resin seems to held really well, and once cured, is very durable, so I’m going to try using that
